Experimental results show that martensitic phase transformations in shape-memory alloys occur in localized zones. Based on a micromechanical model we want to simulate these effects. The mathematical treatment is accompanied by a finite-element calculation which includes, due to the model modification, a regularization. The result of this effort is a micromechanically well motivated algorithm which shows qualitatively a good agreement with experiments. Numerical examples are presented.
