Shape memory alloy (SMA) have presented excellent behaviour for medical applications such as bio-compatible, high corrosion resistance, non-magnetic, and the unique physical properties, which replicate those of human tissues and bones. Based on the experimental results of super-elastic NiTi alloy, a three-dimensional super-elastic shape memory alloy (SMA) constitutive model for stress-induced martensite transformation is constructed in a framework of general inelasticity. In the proposed model, transformation hardening, reverse transformation of stress-induced martensite, elastic mismatch between the austenite and martensite phases, and temperature-dependence of transformation stress and elastic modulus of each phase are considered. The validity of such implementation was finally presented and compared with experimental data taken from the literature.
