Propagation of Love waves in an initially stressed medium consisting of a slow elastic layer lying over a liquid-saturated porous solid half-space

Abstract

The dispersion equation, for Love wave propagation in a slow elastic layer overlying a liquid saturated porous solid half-space, is derived. Both the media are assumed to be under initial stress. The effect of porosity and initial stress on the phase velocity of Love waves has been discussed. Dispersion curves for the phase velocity have been plotted, both with the presence and absence of prestress, for different values of the sandiness parameter. Some special cases have also been deduced.
