This paper is considered the problem of stationary shock wave propagation in a two-phase porous material — an incompressible viscoplastic medium containing spherical pores with a surface coating (an incompressible viscous fluid). A hierarchy of simplified analogs of the basic mathematical model for temperature field formation in a shock-compressed porous material is developed. It is shown that the use of simplified analogs of the basic model significantly reduces computational costs during numerical experiments. Conditions are determined under which, if satisfied, the simplified analogs of the basic mathematical model enable the temperature field of a two-phase porous material to be accurately identified under shock-wave loading.
