(eng): Evolution of fine structure in martensite undergoing an isothermal process is modeled on a microscopic level by using a positive homogeneous dissipation potential which can reflect a specific energy needed for a phase transformation between different variants of martensite. The model thus naturally incorporates an activation phenomenon. Existence of a weak solution is proved together with the convergence of finite-element approximations. Numerical experiments are also presented.
