Численное решение пороупругого волнового уравнения с использованием метода конечных элементов

Abstract

In the article, we investigate the problem of acoustics in porous media in three
separate areas. In each area, it is assumed that the materials have different physical properties. Geometry of pore, fluid viscosity is located in the middle of two elastic areas. In this problem, we first consider the solution of differential equations. The mathematical model of these physical phenomena is described by initial-boundary value problems for complex systems of partial differential equations.
