Abstract
Based on the experimental results of super-elastic NiTi alloy, a three-dimensional thermo-mechanical constitutive model which includes transformation and plasticity was constructed in a framework of general inelasticity. In the proposed model, transformation hardening, reverse transformation, elastic mismatch between the austenite and martensite phases, and temperature-dependence of elastic modulus for each phase are considered. In the meantime, the plastic yielding of austenite or martensite occurred at high temperature or under high stress is also addressed. The predict capability of the proposed model was verified by comparing the simulated results with the correspondent experimental results.
