Abstract: A complex model for supercomputing the parameters of radiation-induced thermomechanical fields in heterogeneous media of complex dispersed structure is developed. A technique for calculating the parameters of the photon-electron cascade generated in the object by the interaction of radiation with matter is constructed. A geometric model of the medium with a direct resolution of its microstructure is worked out. A part of the geometric description of the medium is a model of the detecting system for the statistical evaluation of the energy deposit density of radiation. The ideal hydrodynamic Euler model of the compressible medium dynamics in a conservative form is chosen as the basis for the modeling of thermomechanical processes. The results of demonstration calculations of thermomechanical fields parameters are presented.

Keywords: mathematical modeling, ionizing radiation, thermo-mechanical effects, the dispersed structure.
