ABOUT FORMATION OF NONEQUILIBRIUM (ACTIVATED) STATE OF MATERIALS UNDER EXTERNAL LOADING

摘要

In term of modern thermodynamics, the behavior of deformable media under irreversible conditions can be described with the help of so called additional parameters, the introduction way of which in the medium model could be various. Additional parameter reflects the insertion of additional degrees of freedom in the system state formation; contributes in the heat capacity, the values of elastic modules, thermal expansion coefficients and other physical-mechanical parameters determined by the second derivatives of thermodynamic potentials.
