Love Wave Propagation in an Anisotropic Viscoelastic Layer Over an Initially Stressed Inhomogeneous Half-Space

摘要

Love-type surface wave in a model comprising of an orthotropic viscoelastic layer supported by a half-space is investigated. The layer and half-space both are heterogeneous, and the half-space is in the state of initial stress. Employing relevant boundary conditions, frequency equation is derived, based on which numerical computations are carried out to analyze the impact of different parameters on Love wave speed. It is discovered that dissipation function and heterogeneity of the layer and initial stress and heterogeneity of the half-space has a substantial effect on phase velocity.
