抄録

The inelastic behavior of shape memory alloy under multi-axial loading conditions were investigated by applying the combined loads of axial force and torque to the thin-walled tube specimen made of Cu-based shape memory alloy. In this paper, some quite unique behavior obtained by the experiments are shown and discussed, which can not be observed in the uniaxial experiments, including the path dependency created by the change of microstructure(especially several number of variants operate simultaneously). The results obtained here manifest the significance of the constitutive equation formulated on the basis of the semi-microscopic approach in the 1st report.
