Effect of Shape Memory Alloy Wires on Natural Frequency of Plates
In last decades, smart materials have developed extensively, and have become an important topic for re- searchers in different areas. SMA is a good candidate for active control of the smart composite structures. In this study, numerical-based analysis for evaluating the natural frequencies and mode shapes of the plate with embedded shape memory alloy wires are presented. Plates are modelled in according to classical plate theory (CPT) as well as first-order shear de- formation plate theory (FSDT). Also, SMA wires are modelled as a beam. The effect of axial load generated by SMA wires due the change of temperature on the natural frequencies is accurately studied.
