Abstract
Ultrasonic scattering by cracks which break the traction-free surface of an engineering structure is of considerable interest in the field of nondestructive evaluation, especially when the crack mouth is inaccessible to direct observation. Considerable effort has been expended in obtaining solutions to the two-dimensional problem, from which much has been learned. A representative cross-section of work on the two-dimensional problem includes papers by Mendelsohn, et al. [1], Achenbach and Norris [2], Datta and Shah [3], Zhang and Achenbach [4], and Roberts [5]. However, if the crack dimensions are comparable to the width of the interrogating ultrasonic beam, the full three-dimensional problem must be considered. To this end, Budreck and Achenbach [6] investigated the scattering of elastic waves from a 3-D normal edge crack of arbitrary shape.
