Abstract

The superelastic behaviour of shape memory alloys is now successfully modelled. On the other hand, the anisothermal creep is badly described, both by phenomenological models and by micro-macro formulations. In this paper we introduce a new approach, based on the concept of group of variants to more precisely describe the microstructure obtained during stress assisted two way memory. A new variants selection criterion is proposed.
