Abstract

The elastodynamic problem of the diffraction of stress waves by a crack near an interface is considered. Using integral transform techniques the case of a crack perpendicular to the interface is reduced to a system of singular integral equation. The stress intensity factors at the crack tips are calculated by numerical techniques over a range of frequency for different material properties and crack distances from the interface.
