Modeling of shape-memory alloys on the mesoscopic level

Abstract
This contribution presents some recent results on modeling of phase transformation in the pseudo-elastic regime within the framework of continuum mechanics. We recall an efficient concept for quasi-static evolution of microstructure in the isothermal rate-independent case. We then concentrate on simulation results obtained by the presented model, performed on a single-crystal prismatic NiTi-specimen. Algorithmic details, i.e. energy-estimates-based optimization, are also given.
