Theory of Martensitic Phase Transitions in Elastoplastic Materials

Abstract
The conditions of nucleation, nondisappearance of nucleus and interface propagation are derived for noncoherent and coherent phase transitions (PT) in elastoplastic materials. Extremum principles for determination of all unknown parameters are derived based on the postulate of realizability. Two model problems are solved. The predicted effect of shear stresses and plastic strains on PT pressure and hysteresis is in qualitative agreement with experiments.
