Ultrasonic C-scanning uses waves ropagating normal to a plane surface. This is accurate, but slow for planar structures. Longitudinal waves would allow quicker testing of such structtwes. This paper considers the reflection of low to moderate frequency Rayleigh Lamb waves by a through width lozenge-shaped defect in an isotropic plate. A numerical method is used. It is shown that such longitudinal ultrasonic waves can be used with success to detect and locate structural defects if care is exercies in frequency selection.||Type of material:||Journal Article||Publisher:||Wiley||Journal:||Zeitschrift fur Angewandte Mathematik und Mechanik||Volume:||81||Start page:||S975||End page:||S976||Copyright (published version):||2001 Wiley||Keywords:||Rayleigh-Lamb waves; Crack detection; Ultrasonics||Language:||en||Status of Item:||Peer reviewed|
