Abstract

The stress-strain relationship and phase transformation behavior of shape memory alloy (SMA) in pure shear state are investigated by using Zhou's SMA micromechanical constitutive equation of 3-dimension and Zhou's SMA phase transformation equation of 1-diemsion respectively. Then thermo-mechanical model describing thermo-mechanical behaviors of SMA torque thin-walled tube is established based on the stress-strain relation and phase transformation model of SMA in pure shear state. The relations of torque vs. rotation, recovery rotation vs. temperature and recovery torque vs. temperature of the torque tube are numerically simulated by using the thermo-mechanical model.
