My Pivotal Unique Feature
A multidisciplinary/multi-physics/cross-disciplinary researcher, educator, supervisor, and engineer
Based on my curricula, it can be concluded that I have multidisciplinary/multi-physics/ inter-disciplinary engineering, instructional, supervising, and research characters and skills. I have started my higher education studies and research from civil engineering with strong emphasis on matrix structural dynamics, design and analysis of bridges (during my BSc at SUT) to structural mechanics/ engineering, and applied/computational mechanics, specifically, nonlinear finite element analysis (FEA) (during my MSc at SUT) to multi-body/computational dynamics, specifically, computer-aided analysis (CAA) of aerospace structures and mechanisms (during my PhD at UofA) to earthquake engineering, electronics/control engineering, and structronics, specifically, adaptive/semi-active control of nonlinear structures (during my PhD at SUT). Therefore, I have both widened and deepened my academic studies, skills, and research, starting from civil engineering/structural design (BSc), structural engineering/computational mechanics (FEM/SEM) (BSc/MSc/PhD), and earthquake engineering/ structural dynamics/vibration control engineering/semi-active/ active/ passive structural control (MSc/PhD) fields to mechanical engineering/ applied/ continuum mechanics (MSc/PhD), aerospace engineering/multi-body dynamics (MSc/PhD) and electrical engineering/electronics/control engineering (PhD), to smart structures/piezoelectric materials, adaptronics, composite structures/FGM, spectral element methods, axially moving structures, machine learning (ANN, SVM, GA/GP, computer vision), SHM/damage detection/ ultrasonics/ structural system identification, FSI, nano-mechanics, mechatronics, and stochastic vibration/control (assistant professor position at IUT and UI), then, nowadays, to opto-mechatronics, bio-mechatronics, soft robotics, and MEMS (associate professor position at IUT). As a result, I am capable of conducting research, teaching, supervising, and doing engineering design and practice in cross-disciplinary fields of structural engineering, earthquake engineering, civil engineering and engineering mechanics, mechanical engineering, aerospace engineering, and control engineering, as well as applied and computational mechanics, electronics, structronics, mechatronics, opto-mechatronics, bio-mechatronics, soft robotics, intelligent dynamic systems, MEMS/NEMS, and the related subfields.
In my idea, there should be no strong border lines among different engineering and applied science fields. Even as a more revolutionary idea, I believe that an engineer or scientist with expertise in dynamic systems may work on economic, social, or educational sciences in order to domesticate and capture these human behavioral-based dynamic systems to mathematical, computational, and/or experimental models and formulations, although s/he may be enforced to implement statistical concepts like structured/unstructured parameters or variables present during the dynamic model construction, mathematical formulation, analytical and/or numerical solution and simulation, experimental setup, signal processing and data interpretation, and result validation and/or verification.
Summary of My Top Achievements in my Fields of expertise:
(FEM/CSD, SSM/AVC, ECM/DSI, SHM/CSM, FSI/NEMS, EHS/MEMS, DST/CPS)
- Publishing many international/national journal and conference articles on these fields.
- Earning rank first among 14 Masters’ level students at SUT.
- Earning rank first for research activities among 5 PhD students at SUT.
- Earning rank fifth among about 100 Bachelors’ level students at SUT.
- Earning many prizes during my MSc, PhD at SUT, and during my assistant and associate professorship at Isfahan University of Technology (IUT) and University of Isfahan (UI).
- Education and research at borderlines of established fields like (1) Civil (2) Structural (3) Mechanical (4) Aerospace (5) Electronics (6) Control & (7) Computer Engineering, I think and believe in that my multi-disciplinary specialty is unique and valuable for Industry 4.0 age.
- Specialist in piezoelectric structures and materials for designing sensor and actuator transducers.
- Specialist in electromechanical finite element and spectral element modeling, analysis, and design of structures, like civil, mechanical, aerospace, automotive, marine, biomedical, and micro/nano.
- Specialist in seismic design of building, bridge, dam, off-shore, & on-shore, structures.
- Specialist in theoretical/computational modeling/analysis/design of MEMS/NEMS transducers.
- Teaching a lot of diverse undergrad/graduate engineering and mathematics courses as tabulated.

I think if it could not be unique, it should be rare teaching so many diverse courses, of course during 30 years of teaching at university level (1990 t0 2020).
Teaching philosophy and approach
At present at IUT, we use Farsi MOODLE for uploading our course and online education. I upload my lectures by ACTIVEPRESENTER in MP4 format, then after hearing and observing by students, I arrange Q&A online classes as well as I pose a mini-project to be solved by students based on the information given in a package of lectures equal to a text chapter. At end, I propose some term projects to be solved based on the all information given in the course. In this way, I make the students study and apply their capabilities to apply the presented information in mini-projects as well as a course project. In between, they will solve some problems and apply their information to prepare home works as localized challenges to be solved by methods presented in the course.
We academics, as a part of Globe community, are stepping forward from information age to Internet of Things (IoT) age. We have to try to stay ourselves above the waves transforming the societies before being submerged, I mean we must accept the natural selection based on adaptivity and smartness for elites to survive even in didactic or pedagogical events. Therefore, the principal directions of my academic teaching and research are categorized as having potential for tolerating the change, evolution, and adaptiveness, for accepting the dawn of IoT age (age of Internet of Things, AI and machine learning), more listening to the audience (specifically to the students and colleagues) than speaking as a single-mode lecturing, as well as sharing, recycling, redirecting, and pruning our past knowledge and thoughts with those of our audience, prohibiting from prejudice of students, preventing from discrimination among students, but only for the scientific merit, of course.
Please refer to the attached documents (in Farsi and English) as concrete samples for my teaching practice and a number of concrete examples for teaching experience, the scope of teaching, pedagogical requirements, teaching formats, and feedback methods. However, some comments are needed for more clarification.
First of all, because the scope of my education, curriculum, and research has cross-passed from civil to structural, to earthquake, to mechanical, to aerospace, to control, to electronics, to mechatronics, finally, to bio-mechatronics engineering sciences, I believe that these roadmaps and approach have had strong influence and interaction on my teaching philosophy and practice. For example, more often than not always, when I present a course of “Advanced vibrations” for the current term in chalk and talk style (my favorite method in contrast to merely PowerPoint slide deck), I cannot convince myself to present that course for the upcoming term word by word as I did in the current term. I may change and modify iit by about 20-30% new materials in the context of subject but based on the current needs and the latest directions of research and advices by challenges of both the Globe and local society.
As a less serious comment, for instance, in the current term, I would try to connect the “Advanced vibrations” concepts to the formulation and solution of a dynamic system of first order ODEs (ordinary differential equations) for identifying, localizing, quantifying, and predicting the mechanism, spatial, and temporal distribution and interaction of people with positive corona virus tests, and predicting local areas subject to a threshold corona virus pollution and whether those areas which the rate of defection is decreasing or not, and so on.
A brief comment is given about receiving feedback from my students and colleagues. Since one of my expertise is “feedback control of dynamic systems”, I strongly believe that the output of any system (here, response of students and my colleagues to my teaching) should be compared, modified, amplified, and corrected (the comparator and processor/controller) by a reference (here, a model reference teaching practice and didactic concepts). If the dynamic system of my pedagogical methodology would be passive, I could not adapt and evolve my didactic methods, while I would be submerged by the waves of the IoT age as well as AI learning systems.
As a matter of fact, if I could explain what novel courses I wish I could establish in any department, I would reply in this way. I hope, with the cooperation and advices of my colleagues in any department, I could establish and offer some of the following courses:
- (1) Smart/adaptive dynamic structures and systems (SS/AS), (2) Sensory/sensitive structures and systems, (3) Mechatronics/Structronics, (4) Machine learning/MEMS-embedded structures (MEMSS), (5) Structural health monitoring (SHM) or Machine monitoring
Finally, as I tried to outline, my hub of teaching and research philosophy are circled around adaptiveness and smart evolution (my ideas) but not based on a random selection phenomena. I emphasize, based on adaptive learning, and combining carbon-based intelligence together with silicon-based one.
Research philosophy, approach, and directions
My research directions and philosophy has evolved during past years. In 1985, when I was a senior student at Sharif University of Technology, I took courses on “Matrix Structural Analysis”, “Structural Dynamics”, and “Bridge Engineering”, I got interested in seismic or dynamic structural design of bridges and became a design/project engineer, so I selected my BSc project on: “Matrix Structural Dynamics, Analysis & Design of Highway Bridges of four types: Steel Truss Bridge, Steel Orthotropic Deck Bridge, Composite R/C-Steel Deck Bridge& R/C Deck Bridge”
In 1986, as soon as I took a course on FEM at the beginning of my MSc curriculum at Sharif University of Technology, I decided to start my MSc thesis on Computational Structural Dynamics. My academic Master and Sheikh became Prof. Klaus J. Bathe. Then, I got interested in Finite Element Methods, specifically, nonlinear solid and structural mechanics and dynamics problems. I selected my MSc thesis to conduct research on: “Nonlinear Geometric & Material Finite Element Stress Analysis”. In 1990, I wrote my first conference paper, entitled: “An Assessment of Solution Algorithms of Nonlinear Equations Due to FEM Discretization in Nonlinear Structural Mechanics with Emphasis on BFGS”.
During my military service, from 1990 to 1992, I served as a lecturer in the department of aircraft engineering at the University of Aeronautical Engineering. So I got interested in matrix design/ analysis of aircraft structures. This became my eagerness to follow my PhD in aerospace structures.
During my stay in the department of Aerospace and Mechanical Engineering at The University of Arizona, from 1993 to 1994, my research focus turned toward multi-body dynamics and computer-aided analysis of mechanical systems, as proposed to me by Prof. P.E. Nikravesh.
After that, during my PhD at Sharif University of Technology, from 1994 to 1999, I got interested in Earthquake Engineering, specifically, “Nonlinear Dynamics and Adaptive Control of Structures”. So this field became my principal research theme in my remaining academic life. This, in addition to closely-related research subjects of Smart Structures and Materials (SSM), Structural Health Monitoring (SHM), Composite Structurs & Materials (CSM),Finite Element Model-Updating, Passive Control of Viscoelastic Structures, and Stochastic Structural Dynamics were the major theme during my research as full-time assistant professor in the departments of civil engineering, from 2000 to 2007.
From 2008 until present that I have changed my affiliation to the department of mechanical engineering, I have continued those previous topics, but with a taste of more mechanical and aerospace structures than civil and off-shore structures. These mechanically-oriented research themes are, from the oldest to the latest, Fluid-Structure Interaction (FSI), Eenergy Harvesting Systems (EHS),MEMS/NEMS, nonlinear structural mechanics, random fields and excitations, mechatronics, vibro-acoustics, opto-mechatronics, biomechanics, and the latest are bio-mechatronics.
In brief, I may divide my principal fields chronogically based on the following table:

As a matter of fact, my research has turned direction from more theoretical and computational mechanics research toward more mechatronics-oriented product design and manufacture. At present, I and my graduate students team are working on the product-based projects of Adaptive Focus Liquid-Lens Eyeglasses and Liquid Crystal Contact Lens, Wire-less Lead-less Cardiac Pacemakers, Artificial Mitral Valves by SMA, and the like.
Research activities (By chronological order)
My research directions and philosophy have evolved during past years. I may partition my viewpoint into eight time intervals, based on a chronological order of my growth in academic life.
a) BSc curriculum at SUT (1979-1986):
In this period, I was immature and less educated in doing research. In 1985, during my senior undergraduate at Sharif University of Technology, I focused on design projects. My BSc design project was Matrix Structural Dynamics, Analysis and Design of Highway Bridge Structures of four types: (1) trussed, (2) orthotropic steel deck, (3) R/C deck, (4) composite steel/concrete deck bridges. In this period of my academic life, my research viewpoint is more design-oriented than analytical.
b) MSc curriculum at SUT (1986-1990):
In 1986, as soon as I took a course on FEM at the beginning of my MSc curriculum at Sharif University of Technology, and I got familiarized by the 1982 edition of “Finite Element Procedures in Engineering Analysis” textbook of Prof. Klaus J. Bathe, he became my academic Master and Sheikh. I found my interest on the topic of Computational Structural Dynamics by FEM, starting my MSc on computational structural mechanics, specifically, on nonlinear solid/ structural mechanics problems. I selected my MSc thesis to conduct research on: “Nonlinear Geometric and Material Finite Element Stress Analysis of Continua by BFGS Algorithm”. In 1990, I wrote my first paper, entitled: “An Assessment of Solution Algorithms of Nonlinear Equations Due to FEM Discretization in Nonlinear Structural Mechanics with Emphasis on BFGS”. During this period, I did some unpublished research on the structural design of composite RPV. In this period of my academic life, my research viewpoint is more computational/analytical-oriented than design. The textbook of “Finite Element Procedures in Engineering Analysis” by Prof. K.J. Bathe became a launcher for throwing me inside computational structural dynamics field and even further, this text showed me that there is no difference among different physical systems and their fundamental physics principles, whenever these systems are modeled by mathematical analysis, specifically by calculus, differential and integral equations (ODEs, PDEs, Green’s functions, variational calculus), and finite/infinite dimensional vector spaces; finite for lumped-parameter and infinite for distributed-parameter modeling. This finding started my interests in system dynamics field (as well as feedback control) circumventing structural dynamics. This drove me toward active structural control during my PhD program.
Partial abstract of my MSc thesis (1990)
In this thesis, I developed nonlinear finite element algorithms for 2D plane stress, plane strain, and axisymmetric solids and continua subjected to large rotations, large deformations, and large strains like the extrusion and forging metal forming manufacturing processes. The problem formulation is highly nonlinear from geometry, material, and boundary conditions viewpoint. The analysis needs automatic re-mesh generation for avoiding non-convex finite elements to be generated. The solution procedure is based on two nested iteration loops, the outer loop for incremental load steps, and the inner loop for convergence between external incremental loads and generated internal incremental stress states in any discrete point of the structure. Transforming nonlinear PDEs of time-dependent and space-dependent to either nonlinear ODEs (time-dependent dynamic problems) or nonlinear algebraic equations (static problems) by finite element discretization properties establishes a system of highly nonlinear equations to be solved. In the case of nonlinear ODEs the discretization process continues with Newmark’s β method. In any case, these nonlinear algebraic equations are solved by BFGS algorithm which is inherently an optimization solver. In the nonlinear continuum mechanics formulation, I have used Green-Lagrange strain tensor measures and 2nd Piola-Kirschhoff stress tensor. For coding my algorithms, I have used FORTRAN 77.
c) Military Service at University of Aeronautical Engineering (1990-1992):
During my military service, from 1990 to 1992, I served as a lecturer in the department of aircraft engineering at University of Aeronautical Engineering of Iranian Air Force Army. So I got interested in matrix structural dynamics/design/analysis of aircraft structures. This triggered my decision to follow my PhD in aerospace structures. In the military service period, I switched from large-scale civil structures toward large-scale aerospace structures.
d) PhD curriculum at University of Arizona (1993-1994):
During my stay in the department of AME at The University of Arizona, from 1993 to 1994, my research focus turned direction toward multi-body dynamics and computer-aided analysis of mechanical systems, as proposed to me by Prof. P.E. Nikravesh.
e) PhD curriculum at SUT (1994-1999):
After that, during my PhD at Sharif University of Technology, from 1994 to 1999, I was interested in EarthquakeEengineering and Nonlinear StructuralDdynamics and Adaptive Control of Structures. I conducted research on model-reference adaptive control (MRAC), semi-active switching control, model predictive control (MPC), robust control, and stochastic system parameter and state variable estimation algorithms, specifically filtered-x LMS and extended Kalman optimal filtering algorithms. I wrote my codes by MATLAB and Simulink. These research subjects, crystallized in the “Smart Structures & Materials”, become my principal research theme in my remaining academic life.
Partial abstract of my PhD thesis ((1999)
In this thesis, I developed and implemented several nonlinear structural feedback and feedforward nonlinear controller/observer algorithms, specifically for finite element discretized continuous framed structures subjected to nonstationary non-Gaussian input signals as well as seismic records of strong motion. Nonlinearity for structures is a type of time-varying boundary conditions and of control algorithm is due to off/on commands and/or time varying static (stiffness) and dynamic (damping) properties of the structures. In addition, the adaptive type of control strategies has benefitted from a stochastic parameter and state estimation approach. Stochastic extended Kalman filtering has been implemented for estimating state variable signals (acceleration, velocity, and displacement), while filtered-x LMS has been used for estimating the system properties (stiffness and damping properties). Three important control strategies I have developed are: (1) model-reference adaptive control (MRAS), with two loops one inner loop for turning back the feedback state variable signals for comparison with reference model and the outer loop, a parameter identification/estimation algorithm for estimating time-dependent parameter variables, (2) model predictive control (MPC), with a horizon for extrapolation of state variable signals resulting from updated model and (3) robust control, with structured uncertainty blocks (by knowing a priori, either a specific probability distribution/density function of inputs or their auto-correlation/ cross-correlation functions) resulting from Bayes’ theorem and statistics (past information). My codes is developed in the environment of MATLAB, its toolboxes, and Simulink.
f) Assistant Professor of Civil Engineering at IUT (2000-2003):
I did research on “finite element dynamic model updating by frequency response function Matrices and system output error model”, “dynamics/passive controls of seismically-excited viscoelastic structures of tall buildings”, and “stochastic dynamics finite element model updating by Bayesian theorem and random vibration techniques”.
g) Assistant Professor of Engineering Math at UI (2003-2008):
The theme of “Smart Structures & Materials”, in addition to closely-related research subjects of structural health monitoring (SHM), piezoelectric smart structures, finite element model-updating, passive control of viscoelastic structures, and stochastic structural dynamics were my major research themes.
h) Assistant Professor of Mechanical Engineering at IUT (2009-2013):
During my return to Isfahan University of Technology but this time, the department of mechanical engineering, my research directions turned towards mechanical engineering applications of structural dynamics and smart structures and got more interdisciplinary. I conducted research on dynamic system identification of structures, structural health monitoring (SHM) and structural damage identification, NEMS and scale-dependent elasticity and continuum mechanics.
i) Associate Professor of Mechanical Engineering at IUT (2013-2020):
From 2008 until present that I have changed my affiliation to the the department of mechanical engineering, I have continued those research topics in my stay in the departments of civil engineering, but with a taste of more mechanical structures and applied mechanics than civil structural mechanics and engineering. These mechanical-oriented research themes are, from the oldest to the latest, fluid-structure interaction (FSI), MEMS/NEMS, nonlinear structural dynamics, random fields/vibrations, composite plate and shell nonlinear vibrations, energy harvesting systems (EHS), mechatronics, vibro-acoustics, opto-mechatronics, and the latest are bio-mechatronics.
As a matter of fact, recently, my research has turned direction from more theoretical and computational mechatronics research toward more innovative designs and mechatronics-oriented product design and industry 4.0-based manufacturing. At present, I and my graduate student teams are working on the subjects of adaptive-focus liquid-lens eyeglasses, wire-less lead-less cardiac pacemakers, artificial mitral valves by SMA, and continues.
Research plans for the next coming years
Based on present conditions of our world, I am predicting that my research plans may be divided along the following fundamental directions:
- Structural Dynamics/Mathematical Analysis, i.e., multi-physics system modeling, analytical (physics-based), numerical (computer-based), and experimental (data-based) formulation, Monte Carlo simulations, and deterministic/stochastic solutions, validation/verification, structural/system identification/finite element model updating, and data interpretation/discussion, and parametric/case studies.
- Machine Learning-based Dynamic Systems Synthesis, Analysis & Design, 3D Print-aided Manufacturing.
Engineering/Mathematical Analysis phase is divided among the following areas:
- The most favorite direction, under the influence of my PhD curriculum, should be Smart structures and materials, Adaptive structures, Intelligent structures, Active structures, Electronic structures, Piezoelectric structures and materials, Structronics, Mechatronics, and so on. The specific topic shows the level and grade of intelligence and adaptivity. I am also working in the subfields of Structronics, i.e., Structural health monitoring (SHM), Structural system identification (SSI), Structural damage detection, Energy harvesting systems (EHS), and so on. In fact, this branch of engineering knowledge brings together the subdomains of (1) Dynamics (structural dynamics and vibrations), (2) Electronics and Controls (actuator and sensor technology), and (3) Computer Science (AI and machine learning).
- I have been changing my research direction continuously toward a greater circle, i.e., Smart systems and intelligent machines, including multi-physics systems of mechanical, electrical, magnetic, thermal, optical, hydraulic, pneumatic, chemical, and biological phenomena and characteristics, and multi-physics modeling by analytical/ theoretical, computational/ numerical, and experimental/ laboratory methods. Up to this date, I have touched the interdisciplinary fields like, bio-mechatronics, opto-mechatronics, fluid-structure interaction (FSI), MOEMS and NOEMS.
- The third line of my research, as before, would have more attention towards data-driven modeling of multi-physics dynamic systems, using AI, machine learning, machine vision, and upgrading those dynamic models with mathematical and fundamental physics-driven modeling of dynamic systems.
- I am going to conduct research on soft robotics with my previous knowledge on structural and system dynamics, adaptive control, robust control, and multi-body dynamics.
- I am going to establish effective teams of younger faculty members/postdocs and graduate/ undergraduate students to convert and promote the conceptual and brainstormed mechatronic designs to manufactured rapid prototypes and pilot products. For this target, I need grants from industry, government, and academia. In addition, I am insisting on organizing an equipped Industry 4.0 AI-motivated laboratory for completing a mechatronics project from zero to one hundred.
Added value of my activities to the prospective department, campus, and university
If I would join any department, I would be one gear (one single faculty member) of a huge gearbox (the campus). Therefore, I could be of value based on the above-mentioned research directions, if the whole system (campus) could move forward, translate, and rotate intelligently and efficiently. I, as a single gear, try my best to move forward this gearbox as much as I can.

Grants/Funds
In Iran, grants and funds, received by faculty members, are managed and distributed by the affiliated universities of the faculty members (in my case, IUT), which are governed themselves by the Iranian Ministry of Science, Research and Technology. The grants are severely limited due to economic instability and distributed probably by prejudice far from scientific merit. I have received grants from 2005 in IR Rial, but if it is exchanged to international currencies (if possible), nothing valuable remains for conducting experimental research and providing laboratory facilities. This is one of my reasons for leaving my current affiliation at IUT.

List of publications
In all of the following published articles which I have a role as an author, I am also the supervisor or advisor for the first author who is my student (graduate/undergraduate) or one of my graduated students. For triggering the study and research, first I look for the latest works on the cutting edge of engineering knowledge available open literature and on the Internet, which are surrounded by my previous expertise or my interests with links to my fundamental engineering knowledge. I brainstorm, conceive, classify, organize, generalize, and present the core idea for more search, literature review, study, research, and feedback from my students, in general and private sessions that I have periodically with my students. Normally I have a weekly general meetings with all of my graduate and undergraduate students in separate sessions, as well as private meetings whenever necessary. Off and on I introduce the latest peer-reviewed journal papers in the subject to my students. I advise and guide them in research methodology, e.g., pruning my ideas by more search and study, encouraging them for more brainstorming without any fear for being an impossible mission and/or contradicting fundamental laws of continuum physics, i.e., (1) & (2) conservation of linear and angular momenta, (3) conservation of energy (the first law of thermodynamics), (4) conservation of mass, (5) conservation of electric charge, (6) no possibility for decrease in entropy (the second law of thermodynamics), (7) & (8) Gauss’s laws for electricity and magnetism, (9) Ampere’s circuital law, and (10) Faraday’s laws of electromagnetic induction, crystallizing concepts, establishing simplifying hypothesis, transforming physical systems to mathematical models, formulating models to analytical tools, e.g., (1) establishing ordinary/partial differential equations (ODEs/PDEs) having independent variables in time and/or space or more abstractive, establishing infinite/finite dimensional vector spaces in a more general context, (2) building system matrix impulse responses/matrix frequency response functions for lumped-parameter systems, or system Green’s functions for distributed-parameter systems, (3) constituting energy functional terms and applying variational calculus and energy methods, and solving the formulated model by analytical/theoretical, computational/numerical simulation, and/or experimental/laboratory tools, interpreting the results, performing parametric/case studies, comparing, verifying, and validating by the work of other researchers, documenting and customizing a detailed version of our achievements for thesis and a more compact version for paper publishing in an authentic journal.

Phase I:
To invent a pair of eyeglasses, which lenses are transparent silicon liquid inside a mini-pump whose piston translate approximately back and forth by turning a small screw on the rim supporter of those lenses. This translational movement, in fact, is a combination of both translation and rotation about a fixed axis. The diopter range of this pair of eyeglasses is about 3 to 4. The major advantage is that it can change from convex shaped-lens with positive diopter (near-sight vision)) to concave shaped-lens with negative diopter values (far-sight vision). So it is appropriate those people with age larger than 40 to 45 and having eye sight refractive errors.

Partial abstract of my PhD thesis ((1993-1999), entitled
“Nonlinear Control and Dynamics of Seismically-Excited Structures”
In this thesis, I develop and implement several nonlinear vibration control feedback and feedforward MIMO controller/observer algorithms, specifically, for nonlinear and/or time-varying MDOF finite element (FE) assemblages. They could be obtained from discretization of continuous-space framed/skeletal structures (1D distributed-parameter systems), like 2D and 3D trusses, continuous-span beams, 2D and 3D frames with rigid diaphragms, and grillages, subjected to non-stationary non-Gaussian continuous-time continuous-valued random disturbance signals or stochastic seismic records. For some active/semi-active/hybrid structural control problems that I investigated, the nonlinearity for structures is a type of time-varying on-off switching BCs (boundary conditions) and that of compensating algorithm is due to on- off command signals and/or time varying static (elastic and/or geometric stiffness) and dynamic (viscous damping) properties of the MDOF structure under control. In addition, the adaptive character of control strategies has benefitted from a stochastic parameter-identification and state-estimation approaches. Stochastic extended Kalman filtering (EKF) has been implemented for estimating state-variable signals (acceleration, velocity, and displacement), while Filtered-X NLMS (Normalized Least Mean-Squares) algorithm has been used for real-time (on-line) identification of the system model (elastic and/or geometric stiffnesses and viscous damping) and system input/output signals (frequency content, PGA/PGV/PGD, and phase-shift) properties. The geometric stiffness and phase-shift properties are estimated for detecting onsets of instability. Three important MIMO semi-active/active/hybrid control strategies that I have developed are as follows. (1) MIMO seismic model reference adaptive control (SMRAS), with two nested feedback loops, one inner feedback loop for turning back the fast-changing feedback state-variable signals and an outer feedback loop, as an identification/estimation algorithm for updating the slow-changing parameter-variable signals. (2) MIMO seismic model predictive control (SMPC), with a horizon for extrapolation of state-variable signals resulting from the existence of model. (3) MIMO seismic modal energy transfer (SMET) among natural and non-natural mode shapes of the structure switching among different linear models in a context of robust control strategy. It consists of structured uncertainty blocks in the switching operation successful or not (by knowing a priori, either a specific probability distribution/density function or auto-correlation and cross-correlation functions) resulting from Bayes’ theorem and available statistics (past information). Three kinds of hardwares would be implemented for actuating mechanisms: (1) A wind bracing on/off switching mechanism with controllable friction bolt connection dampers, (2) An on/off-orifice viscous fluid energy dissipating actuator as the hardware of hybrid compensator, (3) A variable-orifice viscous fluid energy dissipating mechanism, as a continuous counterpart of the case (2). The sensor technology is based on piezoelectric accelerometers, tachometers, LVDTs, and strain gauges, for measuring acceleration, velocity, displacements, and strains in predetermined DOF’s of the key points of the structure under control. The computer routines are developed in the environments of MATLAB, its toolboxes like control and signal processing toolboxes, and Simulink. Some of the results of simulations are as follows. Intelligent structures would get smarter during resonance phenomenon. Sudden switching among different linear models of a structure, having dynamic characterizations far from each other, might render system into the instability threshold. Dissatisfaction of Lipschitz condition for switching control systems might cause inaccessibility to the methods of mathematical analysis. Better performance of stiff structures could be observed in on/off wind bracing actuating mechanism controlled by switching control and predictive control. Better performance of flexible structures would be observed in on/off-orifice damper actuators and adaptive control. On/off-orifice mechanism-based control scheme is more stable than on/off wind bracing-based switching control. Better performance of energy dissipating mechanisms would be observed for earthquake signals having low-pass filter dynamic characterizations. Non-uniformity of convergence would be observed for Markov parameters of FIR filters, which model seismic disturbance in the predictive algorithms. By running predictive algorithms, a more exact identification of earthquake dynamics could result for broadband seismic signals. More desirable performance of adaptive control could be observed for broadband seismic signals as compared to narrowband ones. Better performance of predictive control algorithms could be observed for seismic signals having band-pass filter dynamic characteristics as compared to earthquake records possessing low-pass dynamics. Unsatisfactory performance of both adaptive and predictive control schemes would be observed for short-duration seismic signals as compared to longer duration earthquake records. It could be noticed that proportional viscous damping forces would not be zero-mean random processes in the variable-orifice energy dissipating semi-active systems. Adaptive structural control strategies could be interpreted as a tool for designing nonlinear filters that could mimic the dynamic behavior of the physical structure under control with about a 1800 phase shift. The superiority of adaptive control for structural control could be emphasized as compared to the other investigated strategies implemented in this research.
Partial abstract of my MSc thesis (1986-1990), entitled
“Nonlinear Material and Geometric Finite Element Stress Analysis of Continua by BFGS Algorithm”
In this thesis, I developed nonlinear equation solver algorithms for displacement-based isoparametric continuum MDOF finite element (FE) assemblages based on 2D plane stress, plane strain, axisymmetric solid and general 3D continuum constitutive formulations subjected to large rotations, large deformations, and large strains like the extrusion and forging occurring in metal forming manufacturing processes. The FE procedure is implemented to transform a distributed-parameter system (an infinite-dimensional vector space or a model with infinite DOFs) into a lumped-parameter system (a finite-dimensional vector space or a model with finite DOFs) in spatial domain. The continuous integral formulations are derived by virtual displacements (virtual work priciple) in the case of statics, and by combination of the principles of virtual displacements and D’Alembert in the case of dynamics. The formulations are based on both updated Lagrangian viewpoint (with measures of Green-Lagrange strain and 2nd Piola-Kirschhoff stress tensors) and updated Lagrangian viewpoint (with logarithmic strain and Cauchy stress measures), variational calculus, and tensor notation. The problem formulation is highly nonlinear from viewpoint of geometry, material, and boundary conditions (BCs). Rigid-body large displacements do not cause geometric nonlinearity but rigid-body intermediate and large rotations do. Large displacements may cause nonlinear BCs. Material nonlinearities are due to running material behavior from linear elastic range into nonlinear elastic or even plastic or viscoplastic response. The analysis needs automatic re-mesh generation for avoiding non-convex finite elements to be generated. The nonlinear solution procedure is based on two nested iteration loops. The outer loop is for incrementing load steps (or time steps in the case of dynamics), while the inner loop is for measuring an energy-based convergence criterion between the incremental external equivalent nodal loads and generated incremental internal stress resultants calculated in the Gaussian integration points of FEs of the structure or continuum. Transforming nonlinear (space and/or time-dependent) PDEs into either nonlinear system of (time-dependent only) ODEs (dynamic problems) or nonlinear system of algebraic equations (Static problems) by FE discretization of mass, elastic stiffness, geometric stiffness, and classical viscous (viscoelastic in the case of visco-elastoplastic material response) damping properties remains a system of highly nonlinear equations. In the case of nonlinear ODEs the discretization process continues with one of the most efficient direct and implicit time integration schemes, i.e., Newmark’s β time stepping methods (in the case of structural dynamics or second-order representation of time-dependent ODEs) or Runge-Kutta methods (in the case of state space or first-order representation of time-dependent ODEs) for temporal discretization. In any case, in each load or time increment of loading, these nonlinear algebraic equations are solved by BFGS (Broyden-Fletcher-Goldfarb-Shanno) algorithm, which is one of the most effective procedures of quasi-Newton or matrix update methods. BFGS is inherently an optimization solver. In each iteration, for approaching convergence criteria, I used the direct linear equation solver algorithms based on computer implementation of Gauss elimination, i.e., the active column solution. I implemented the skyline matrix solver for efficient use of computing storage. For part of metal plasticity, I developed algorithms for calculating von Mises yield surface criterion, associated flow rule normality rule), isotropic hardening rule, incompressibility condition, and equivalent stress and strain rates. For coding my algorithms to computer routines and subroutines, I used FORTRAN 77.
