In this work, we study the shape memory alloys (SMA) micromechanical behaviour in the perfect transformation plasticity. This study is based on the kinematical description of the physical mechanisms at the origin of the phenomenon, and on the thermodynamical analysis of the irreversible processes presented by these alloys in such a transformation. The pseudoelastical behaviour of SMA is described by defining a pseudoelastical potential through the Gibbs theory, and by application of the second principle of the thermodynamic. This approach allowed us to incorporate the change of the martensite variants shape in such thermomechanical behaviour and to analyse the hysteretic behaviour of these materials.
