Vibration of buckled composite plates with embedded heat treated SMA wires

Shape Memory Alloys (SMAs) are a group of smart materials which demonstrate two particular non-linear stress-strain behavior, Shape Memory Effect and Super elasticity based on Austenite to Martensite transformation and vice versa. Effects of heat treatment on SMA wire property and the vibration of composite plate with embedded SMA wires are investigated in current study. Heat treatment effects was studied experimentally and transformation temperatures is determined by differential scanning calorimetry (DSC). Since the ABAQUS software is not capable of analysis the shape memory alloy structures, the UMAT subroutine in the software is used to implement the Boyd and Laguodas model to any shape memory alloy finite element analysis in ABAQUS. Extensive numerical results are depicted to provide an insight into the effects of volume fraction, pre-strain and shape memory alloy properties, transformation temperatures and stress- strain curve changing duo to heat treatment on pre and post-buckled composite plate are discussed.
