Contact between the surfaces of a fatigue crack is developed by a variety of mechanisms [1,2], including plastic deformation, sliding of the two faces with respect to one another or the collection of debris such as oxide particles [3]. Consequently, certain characteristic effects occur when the crack is illuminated by an elastic wave. When no contacts are present, a singularity exists in the elastodynamic fields at the crack tip, leading to a set of diffracted fields emanating from the tip. The presence of the contacts modifies the tip diffracted fields and allows energy to be directly transmitted through the crack, requiring modifications in the non-destructive evaluation techniques to detect or size the crack
