Ultrasonic Scattering by Planar and Non-Planar Cracks
Problems of elastic wave scattering by surface-breaking and near-surface cracks are of considerable current interest for ultrasonic nondestructive evaluation. Ultrasonic scattering by planar cracks near or at the free surface of a semi-infinite elastic homogeneous medium has been studied theoretically by many authors. References to recent papers on this subejct can be found in ,  and . Some experimental works on surface-breaking normal planar cracks have also appeared ( – ).
