Finite Volume Method for 2D Elastic Wave Propagation

This article is concerned with a finite volume formulation of elastic wave propagation. It considers a homogeneous domain as well as a domain composed of two homogeneous elastic solids in perfect contact. The interface is parallel to the free surface. In the case of a homogeneous domain, it investigates the usefulness of the method and compares the results to a number of existing methods. In the case of a two-layer domain, it compares the results to an approximate calculation.
