On computing the initial data for modeling of radiation-induced effects in porous materials
An approach to the calculation of initial data for modeling radiation-induced thermomechanical effects in heterogeneous porous materials is developed. The approach is based on the multidimensional approximation of the results of modeling the interaction of radiation with matter on a difference grid designed to solve the thermodynamics equations. The nonlinear regression model is used as an approximation method. A physical and geometric model of the porous medium with a direct account of its microstructure is constructed. The results of the model calculation of thermomechanical effects in a porous barrier irradiated by x-ray photon flux are presented.
