Abstract: A complex computer model of thermomechanical phenomena in a solid deformable material as a result of the action of intense energy fluxes was constructed. An algorithm has been developed for the end-to-end calculation of heating, evaporation, dynamics of vaporized matter and elastic-plastic wave processes leading to destruction in a solid material. A method for dynamic control of changes in the aggregate state of a condensed medium was proposed. Calculations of the destruction of polymer and composite materials under the action of ionizing radiation were carried out. Numerical results are in good qualitative and quantitative agreement with experimental data.

Keywords: thermomechanical effects in solids, end-to-end calculation of gas-dynamic and elastoplastic waves, modeling of fractures and break-offs, dynamic control of changes in the aggregate state.
