Coupled simulation of gasdynamic and elastoplastic phenomena in a material under the action of an intensive energy flux

A complex computer model of thermomechanical phenomena and a method of end-to-end modeling of processes occurring in a solid material under the action of an of intense energy flux have been developed. The dynamics of nonlinear wave processes leading to internal fractures and spalling phenomena in material samples are discussed using the example of calculating the effect on a polymer material. These results can be used in studies of intensive energy flux actions in engineering practice, verify models of volumetric fractures and spallations in brittle solids, and validate wide-range equations of state.
