Description

Many structures, both man-made and of natural origin, are composed of different elastic materials formed in layers. Often the layers are bonded together along common faces, but it can happen that the bonding is not perfect and flaws occur as cracks or regions of poor bonding in the interface. It is of importance to be able to detect these interface cracks, and one of the most practical methods for accomplishing this, in the cases of engineering interest, utilizes the scattering of elastic waves and the subsequent detection of these scattered waves by appropriate transducers. The goal of this work is to contribute to the theoretical basis for detecting the interface flaw by these means.

Elastodynamic Stress Intensity Factors for an Interface Crack in a Layered Half Space
