Thermomechanical behavior of shape memory alloy reinforced glass/epoxy composite beam

摘要

For the given input electric current profile, this paper proposes a method which is able to determine the transient temperature of the beam cross section and the embedded shape memory alloy (SMA) wires. Both the heat resistance at the interface between the SMA and the glass/epoxy beam matrix, and the heat convection between the beam surface and the surrounding air are considered. Based on Brinson's constitutive relation of SMA, an iteration procedure is then used to calculate the strain of SMA wires, and the mid-point deflection of the beam.
