Study on the Mechanical Properties of Ni-Ti-Cu Shape Memory Alloy Considering Different Cu Contents

By adding copper to increase the performance, Ni-Ti-Cu Shape Memory Alloy (SMA), has been widely used in field of engineering recent years. A thermodynamic constitutive model for SMA considering different contents is established this work. Numerical results two contents, as examples, are compared with experimental verify accuracy theoretical Based on verified model, effects content mechanical properties and tensile compressive asymmetric finally discussed, respectively.
