The inhomogeneity effects on love waves in heterogeneous transversely isotropic layered media

Abstract

This paper is concerned with to investigate the effects of inhomogeneities on Love waves in a laterally and vertically inhomogeneous transversely isotropic elastic media composed of a half-space under a layer of finite thickness with stress-free upper surface. The elastic parameters and density are assumed to vary exponentially. This is a two-dimensional problem. To analyse the effects of inhomogeneities numerical computations are performed to obtain the dimensionless phase velocity and dimensionless group velocity. Numerical calculations are done in two particular cases. All the numerical results are plotted graphically and discussed. It is observed that inhomogeneities have significant effect on Love wave propagation in a layered media.
