✦ Synopsis

Stress-and strain-dependent phase transformations (PT), transformation-induced plasticity (TRIP) and its interaction with classical plasticity (CP) are important phenomena in the material behaviour of steel, and they may cause distortion of work-pieces. These phenomena are intensively studied in experiments and their modelling is a current field of investigations. A complex model of material behaviour for simulation and distortion controlling must include the models of relevant phenomena. It is the aim of the current paper to contribute to the formulation of such a model. We use internal variables for describing special effects in the material behaviour in the context of macroscopic continuum mechanics and include them in the thermodynamically consistent modelling.
