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.
