Study Of Multi Layered Composite Shell With Shape Memory Alloy

Abstract

The use of special composite materials has been continuously growing in recent years. Although many applications for composite materials include identified. general research is still being carried out in order to expand this field. New materials and advancements have been explored. One such new application is the coordination of shape memory materials inside composite materials.

In this study certain parts of the dynamic conduct of a multilayered composite shell with shape memory combination wires have been examined. The influence of SMA wires, the orientation and the thickness to diameter ratio and different boundary conditions, on changes in critical load, the natural frequencies and modes of vibration of the shell have been studied and discussed in the present study. The results presented are obtained by the use of finite element method. The analysis both static and modal has been carried out using ANSYS 12.0.

The shape memory alloys possess the inherent ability to change their material properties in particularly their young’s modulus, damping capacity as well as great capacity for the generation of large internal forces. Integrating SMA’s within composite material structures potentially allow the active control of certain static and dynamic behaviour of the integrated structures.
