Abstract

The results of an investigation of the dynamic deformation of porous materials (PM), averaged taking into account the influence of the strain rate and its thermal effects, are presented. It is shown that the approach described enables taking into account the viscous component of the resistance of PM. The coefficient of viscosity and the static resistance σst in the general case change during deformation in accordance with the change in the magnitude of the strain and the adiabatic heating of the material.
