ABSTRACT: This paper aims to build a constitutive model intended to describe the thermomechanical behavior
of shape memory alloys. This behavior presents many facets, among them we have considered the simple way of shape memory, which is one of most important
properties of shape memory alloys. Because of numerous stages of this effect, the
subject was divided into three independent parts. For each part, we
built the corresponding thermodynamic potential and we deduced the constitutive
equations. To make this model workable, we have developed an algorithm. The simulation
was performed using the NiTi as shape memory alloy.
