Some remarks on the modelling of the thermomechanical behaviour of shape memory alloys

Abstract- Our aim is to examine from the continuum thermodynamic point of view, some models predicting the pseudoelastic behaviour of shape memory alloys. We investigate the choice of states variables, the structure of free energy and complementary laws. A special emphasis is made on generalized standard models. In the state of art, there is a lot of progress to do for modelling the behaviour of shape memory alloys. 1.-INTRODUCTION. Our aim is to examine from the continuum thermodynamic point of view, some mo-dels predicting behaviour of shape memory alloys. In any case, we don't claim to be exhaustive, especially the attractive I. Muller [1] approach, based on statistic thermodynamic, is not described here. We present only some classical models
