Paper Abstract

Vibration and resonance of plates are well known problems in designing and analysis of mechanical structures. While these problems are considered during the design process, significant amount of research has been directed to handle the unforeseen loading situations which may lead to catastrophic events. Different types of techniques (passive and active) were developed to prevent these events. Among these techniques, the implementation of the smart materials such as Shape Memory Alloys (SMAs) and piezoelectric ceramics gained importance for controlling the vibrations through damping or altering the resonant frequencies of the parent structures. Composite materials have become major players in building modern and advanced structures especially plates as a consequence; the development of smart composite structures emerged as an area of high interest. In this paper, the feasibility of SMA wires in controlling the vibration of composite plates through altering the strain energy and hence the natural frequency is investigated. The effect of placing the SMA wires in different directions (longitudinal and angularly transverse) over the composite plates will be studied. Computational and experimental work will be conducted to develop the control strategy to control combined vibration situations. Strain energy analysis of the composite panel using laminate theory considerations was used to relate the strain energy alteration in the panel as a result of the SMA actuation to its effect on the laminate stiffness.
