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 thermal dissipation and heat transfer processes on the temperature field formed in a shock-compressed viscoplastic porous material containing spherical pores with a thin layer of plasticizer on the surface of pores in plastic flow. Based on the results, a theoretical estimate is made of the effect of the mechanical properties of the phases on the critical conditions of shock-wave initiation of chemical reaction in the two-phase porous energetic material.
