A Study of Propagation of Love Waves in an Anisotropic Porous Layer Under Initial Stresss

Abstract

The objective of this paper is to study the propagation of Love waves in a pre-stressed anisotropic porous layer which is a sandwich between a rigid layer and a non-homogeneous elastic half-space. Dynamical equations of motion are based on Biot’s incremental deformation theory. Dispersion equations of phase velocity of Love waves have been derived. The impact of anisotropy, pre-stresses, and porosity on the phase velocity are examined in details. It has been observed that the velocity of Love waves increases when the porosity of the layer decreases. Also, velocity of Love waves increases when anisotropy in the layer and compressive initial stresses both are increased. Numerical computations for the velocity of Love waves have been carried out and the results are plotted in different graphs.
