Аннотация:Certain peculiarities of shock and plastic wave propagation in porous media are analyzed using the equations of state of the porous medium which take into account the plastic closing of pores and the medium viscous properties, as well as the equations of motion and conservation of mass. Effects of shock wave velocity, viscosity, yield stress, and porosity on the wave propagation properties are investigated. The condition of existence of shock waves is obtained. The range of parameter values for which complete plastic closing of pores at the wave front and in the region of partial closing of the pore space is determined. The effect of strength and viscosity properties of a porous medium on the behavior of Hugoniot curves is analyzed.
