Application with the experimental results of the Roundrobin of a 3D modelling SMA based on the based on the phase transformation surface identification under proportional loading and anisothermal conditions

Abstract

Abstract. We present a model based on the phase transformation surface of SMA. This model is described per a thermodynamical point of view. We applied this modelling on an experimental part that has been realized by P. Sittner et al. on a nickel titane wire. We had several experimental sets with we could show the performances of our model, in particular when the taking into account of the asymmetry of the yield surface and the respect of the hysteresis width.
