Abstract
Thermo-mechanical behaviors of polycrystalline SMA (Shape Memory Alloy) under uniaxial as well as multi-axial loading with varying temperature conditions have been studied experimentally and theoretically. The experimental results revealed that the stress state, the stress path, the varying temperature and especially their interactions have complex effects on the martensitic transformation and give quite unique deformation behaviors to the shape memory alloy. Based on the model of polycrystalline SMA obtained by the help of crystal plasticity idea, a set of constitutive equations was formulated, which could reproduce numerically the complex behaviors observed in the experiments.
