Abstract

The results of kinetic consideration of nonequilibrium dynamics of electron-phonon system of a crystal in a strong electric field based on a proposed method of numerical solution of a set of Boltzmann equations for electron and phonon distribution functions without expansion of electron distribution function in a series by phonon energy are presented. It has been shown that electromagnetic action excites electron subsystem which by transferring energy to the phonon subsystem creates large amount of short-wave phonons which effectively influence the lattice defects (point, linear, boundaries of different phases) that results in redistribution and decrease of lattice defects density, damage healing, decrease of local peak stress and decrease of construction materials properties degradation level.
