Title: On the thermodynamic conditions at moving phase-transition fronts in thermoelastic solids
Abstract: The main goal of the paper is to establish possible thermodynamic conditions at a phase boundary to describe a propagation of phase-transition fronts in crystalline solids. Classical equilibrium conditions are not valid in the case of fast propagation of sharp phase interfaces through the material during a stress-induced martensitic phase transformation. We propose to extend the equilibrium conditions to the non-equilibrium case in the framework of the thermodynamics of discrete systems. To provide the description of non-equilibrium states, the thermodynamic state space includes so-called contact quantities in addition to usual local equilibrium variables.
