Advance of waves in fluid saturated elastic-viscoplastic porous medium
The behavior of weak discontinuities in an unbounded fluid saturated elastic-viscoplastic porous medium, which generalizes the model of Bingham body. It is shown that in such an environment, there are two types of irrotational waves and a ekvivolyuminalnaya whose velocities depend on the coefficients of the porous medium and the effective masses of the elasto-visco-plastic and liquid phases.Using the mathematical theory of discontinuities, we obtain differential equations and their solutions to determine the intensity and ekvivolyuminalnyh irrotational waves. As an example, shows a plane wave is irrotational
