Viscoplastic Model of Hot Spots in a Two-Phase Porous Material under Shock-Wave Loading

This paper presents generalized results of numerical analysis of the effect of mesoscopic heat dissipation and heat transfer on the temperature field formed in a shock-compressed viscoplastic porous material containing spherical pores with a thin layer of plasticizer on the pore surface in plastic flow. The results of the study are used to obtain a theoretical estimate of the effect of the mechanical properties of the phases on the critical conditions for shock-wave initiation of chemical reaction in the two-phase porous energetic material.
