Based on the experimental identification of the phase transformation surface, a modelling of anisothermal behaviour of shape memory alloys (SMA) is proposed. Within the framework of the thermodynamics of irreversible processes, two internal variables are chosen: the stress-induced martensite volume fraction and the self-accommodating martensite volume fraction. A special attention is paid to take into account the asymmetry between tension and compression behaviours.
