Abstract
The article presents the summarized results of a numerical analysis of the formation of a temperature field in a shock-compressed two-phase porous material in the absence and presence of phase transformations during plastic pore filling. Using mathematical modeling methods, the influence of mesoscopic processes of thermal dissipation and heat transfer on the resulting temperature field is investigated, and its topological features are determined in the presence of molten zones in the shock-compressed porous material.
