On propagation of Love waves in an infinite transversely isotropic poroelastic layer

Abstract

The present paper is devoted for the study of propagation of Loves waves in a compressible viscous liquid layer of thickness h2 and co-efficient of viscosity ηι bounded by an infinite transversely isotropic poroelastic layer and a transversely poroelastic half-space. The equations of motion in transversely isotropic poroelastic solid have been formulated in the frame work of Biots theory. The secular equation has been obtained and is discussed in the limiting case h2 → 0, ηι → 0 such that the ratio h2/ηι is a constant. Further, secular equation is observed for a case of the poroelastic layer is in welded contact with half-space when the thickness of liquid layer is zero for finite co-efficient of viscosity. Several other special cases have been discussed.
