Shape Memory Alloys are widely used in several fields such as aeronautics or biomedical applications due to their unique behaviors (superelasticity, constrain recovery, shape memory). These behaviors originate from a thermoelastic martensitic transformation responsible for the coupling between mechanical and thermal properties observed in these materials. Optimisation of applications dealing with SMA requires the determination of numerical simulation tools able to capture this coupling. This communication presents the implementation into a commercial FEM code of a SMA constitutive law developed from micromechanical considerations.
