abstract = "Porous NiTi{\textquoteright}s mechanical behaviour is similar to the human bone{\textquoteright}s and it shows good biocompatibility which make it an attractive material for biomedical applications. In this study, the aim is to develop a macro-scale phenomenological model to describe the mechanical behavior of porous NiTi SMAs within the framework of generalized standard materials with internal constraints including the porosity as an additional internal variable. The model includes the effect of hydrostatic pressure due to the presence of porosity. The constitutive equation obtained is used to simulate the pseudoelastic compressive response of a porous NiTi. In addition to stress-strain behaviour, evolution of phase transformation and porosity are also calculated. Numerical results show a qualitative agreement with the experimental results in the literature.",
