A Numerical Treatment of the Fluid/Elastic Interface under Range-Dependent Environments.

Abstract

The technique introduced by McDaniel-Lee for the handling of the fluid/fluid interface boundary under range-dependent environments is extended to handle the horizontal fluid/elastic interface boundary. Representative wave equations of the parabolic type are considered in both fluid and elastic media. The required interface conditions, (1) continuity of vertical components of displacement, (2) continuity of vertical components of stress, and (3) horizontal components of stress vanish on the interface, are satisfied with this numerical treatment. A complete theoretical development is presented along with a test example to demonstrate its validity.
