The Analysis of Deflection and Free Vibration of Laminated Composite Plates Embedded With Shape Memory Alloy Fibers by Finite Element Method
Keyword(s):
Abstract In this paper a finite element mode of classical symmetrically laminated composite plates embedded with shape memory alloy fibers is developed. The young’s modulus and recovery stress of SMA are calculated by using Brinson’s one-dimensional constitutive relation. The analysis of deflection and free vibration show that the SMA can reduce the deflection and increase the vibration frequencies significantly, and it is a economical and efficient design to place SMA fibers in the outer-most plies for utilizing their tuning function.
