End-to-end calculation of thermomechanical phenomena in a solid with dynamic control of the aggregate state

D. S. Boykov


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.

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