摘要：

We propose a thermodynamic model for a heterogeneous, aging, viscoelastic medium at infinitesimal strains and analyze the main thermodynamic potentials. We find the conditions for the relaxation measure, which guarantee the Second Law of thermodynamics to be satisfied. Variational principles for viscoelastic bodies at isothermal and adiabatic loading are formulated. The energy ratios for the determination of the interface at the phase transition are derived. We analyze the local melting process in the viscoelastic body at isothermal loading and study the rheology influence on the development of a spherical liquid phase nucleus.
