Propagation of Love Wave in Viscoelastic Sandy Medium Lying Over Pre-stressed Orthotropic Half-space

Abstract

The main objective of the study is to investigate the effects of parameters on wave propagation in a viscoelastic sandy medium lying over an elastic orthotropic half-space under initial stress. The frequency equation for Love waves has been deduced in a closed form. To examine the effects of initial stress, sandiness and viscoelastic parameters, we have calculated the numerical values for phase velocity and attenuation coefficient. The phase velocity and attenuation coefficient have been plotted against wave number of different values of initial stress, sandiness and viscoelastic parameters. It is observed that the phase velocity and attenuation coefficient have been influenced by the increase of proposed parameters. The theme can be of interest for geophysical applications in propagation of Love waves in the Earth's crust.
