Effect of Irregularity and Inhomogeneity on Love wave Propagation in Dry Sandy Layer Bounded by Monoclinic Elastic Layer and Isotropic Elastic Half-space

Abstract

Abstract The present study deals with the Love wave propagation in a dry sandy layer bounded by an upper monoclinic elastic layer and a lower inhomogeneous isotropic elastic half-space. Rectangular-type irregularity is considered at the interface of sandy layer and half-space. Analytical expressions for displacement fields are derived by adopting variable separation method. The dispersion frequency equation for the phase velocity of Love wave is also derived by using suitable boundary conditions. Special cases for orthotropic elastic half-space is discussed. Also the validation with standard Love wave equation is also verified, discussed in the particular case. Significant effects of various parameters like sandiness, irregularity, inhomogeneity and thickness ratio are observed by analyzing the dispersion frequency equation graphically using the MATLAB software. Theoretical results obtained regarding Love wave propagation in the considered model serve as major highlights, having significant relevance in the field of geophysics, materials physics, soil mechanics and earthquake engineering.
