Summary

Dynamics of Smart Structures is a practical, concise and integrated text which provides an introduction to the fundamental principles. The book has been developed to complement the author's new interdisciplinary programme of study at QMUL that includes courses on emerging and new technologies such as biomimetic robotics, smart composite structures, MEMS and their applications and prosthetic control systems. It includes chapters on smart materials and structures, acoustic waves and transmission lines, dynamics of continuous structures, dynamics and control of plates and plate-like structures, the dynamics of piezoelectric media, thermo-elastic and magneto-elastic media, smart sensors and actuators, fibre-optic transducers, and controller design for flexible structures.Practical text developed in tandem with the author's interdisciplinary educational programme of emerging and new technologies Includes extensive treatment of surface acoustic waves Comprehensively reviews the differing smart materials that are employed in the development of the smart structures Includes coverage of the most recent developments in the field of structural dynamics

Author Biography

Dr Ranjan Vepa is lecturer in avionics in the Department of Engineering at QMUL. Since joining in 1984 he has taught undergraduate avionics related courses, and conducted research into the aspects of the design, analysis, simulation, and implementation of avionics and avionics-related systems including non-linear aerospace vehicle kinematics, dynamics, vibration, control and filtering. Dr Ranjan Vepa is a Chartered Engineer and a Member of the Royal Aeronautical Society. In addition to journal and conference papers, he has contributed to the textbook Application of Artificial Intelligence in Process Control and is currently completing a research monograph on Biomimetic Robotics: Mechanisms and Control, due to be published in June 2008 by Cambridge University Press.
