A two-dimensional (2D) Ginzburg-Landau (GL) theory for temperature induced phase transformations in single crystals is extended to incorporate the effects of mechanical and thermal (expansion or dilatational) strain effects. This extension of the GL theory allows the single crystal GL model to be implemented into polycrystalline homogenization schemes. The proposed model is capable of examining the interactions of applied mechanical loading states and phase transformation processes within single crystals.
