A simple model of dissipative processes originally developed for magnetic materials is extended to ferroelastic materials, in particular to shape memory alloys that display a pseudoelastic behaviour. The model based on non-equilibrium dissipative dynamics leads to kinetic equations. The characteristic feature of the model is a three-level response to the acting force field describing the transition between two opposite states of saturation through the intermediate parent structural state.
