Abstract
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.
