Abstract : Modeling martensitic phase transformation in SMAs has become a key to understand the transformation behavior in terms of their temperature and stress response. In the present work a new method based on a statistical physics concept has been developed for the description of transformation kinetics, total strain and their rates in polycrystalline solids undergoing displacive temperature induced phase transformations. As a result the model explains the kinetics and strain evolution for a polycrystal without the requirement of assumptions on internal variables and their constraints. Instead it is based on fundamental properties of the SMA single crystal, only.
