Characteristics of Torsional Wave Profiles in a Viscous Fiber-Reinforced Layer Resting over a Sandy Half-Space under Gravity

Abstract

The current work investigates the propagation of torsional waves at the interface of a Voigt-type viscoelastic fiber-reinforced layer and a sandy half-space under gravity. The media used are prestressed and heterogeneous. The dispersion relation is established in compact form by the variable separable method. The significant effect of heterogeneity, viscoelasticity, fiber-reinforcement, initial stress, sandiness, and gravity on propagation characteristics of torsional waves has been elucidated graphically. The present work may serve as a helpful tool to connect theoretical results and field applications.
