1008 Mechanical Behavior of Ti-Ni Shape Memory Alloy under Tension-Torsion Loading

This paper describes experimental results for stress - strain behavior of Ti-Ni shape memory alloys in the super elastic regime. Cylindrical hollow test pieces were loaded and unloaded by the strain control in the multi-axial (axial-shear) strain space under the proportional loading condition. Test results showed the complicated stress-strain behavior of the material under multi-axial stress-strain states.
