I will discuss well-posedness and long-time behavior of Mindlin-Timoshenko plate equa- tions that describe vibrations of thin plates. This system of partial differential equations was derived by R. Mindlin in 1951 (though E. Reissner also considered an analogous model ear- lier …

Installation of damping devices has been limited to diagonal or chevron brace configurations until the recent development of the toggle-brace configurations. These configurations magnify the effect of damping devices, thus facilitating their use in stiff framing systems. Such sy…
Recent developments in smart materials technology have led to the introduction of intelligent structures. One such approach is the use of composite members filled with electro-rheological (ER) fluids. This study first addresses the scope of research on ER fluid-based composites …
Vibration-based energy harvesting using piezoelectric materials have been investigated by several research groups with the aim of harvesting maximum energy and providing power to low-powered wireless electronic systems for their entire operational life. The electromechanical cou…
