A micromechanics constitutive model for martensite transformation of polycrystalline shape memory alloys is proposed. The model is established on the following bases: (1) the transformation theory of unconstrained single crystal shape memory alloys, (2) the proper simulation for the evolution of microstructure, i.e., nucleation and growth of marten-site variants, (3) the effect of orientation distribution on transformation process. Theoretical predictions of this model are in agreement with the available experimental observations.
