Investigation of flexural vibrations in poroelastic solid sphere in the presence of static stresses

Abstract

In this paper, the three dimensional wave propagation in a homogeneous isotropic poroelastic solid sphere is investigated in the presence of static stresses. The frequency equation is obtained in the framework of Biot's theory. Non-dimensional phase velocity is computed as a function of uniaxial static stress for fixed wavenumber. For the numerical results, three types of poroelastic spherical solids are employed, and the results are presented graphically.
