Presents a model and its computational realization for the simulation of solid-solid phase transformations of the type observed in shape memory alloys. The model includes both mechanically and thermally driven phase changes. It is based on mixture theory combined with a suitable kinetic model for phase evolution and explicitly accounts for reorientation of the crystalline anisotropy and the associated symmetry changes which are essential to the observance of memory effects.
