Elastodynamic diffraction by a periodic rough surface (stress-free boundary)

Abstract
The reflection of an elastic wave by a rough stress-free surface with a periodic profile has been investigated rigorously. The problem is formulated in terms of an integral equation for the particle displacement at a single period of the boundary surface. Numerical results pertaining to the reflection of either an incident P wave or an incident SV wave for a sinusoidal profile are presented.
