|Title:||Attenuation Of Ultrasonic Rayleigh-Lamb Waves By A Symmetrical Embedded Crack In An Elastic Plate||Authors:||Gilchrist, M. D.||Permanent link:||http://hdl.handle.net/10197/5930||Date:||1999||Abstract:||The present paper illustrates how embedded vertical defects can be detected rapidly in sheet metal by using longitudinal ultrasonic waves. Computational methods are used to validate analytical predictions of the reflection coefficients due to the attenuation of such ultrasonic waves by physically small defects. It is shown that detectable attenuation of the lowest order symmetric Rayleigh–Lamb wave (S0) occurs for a range of small defects (sub-millimeter in length) when using high-frequency waves (MHz range).||Type of material:||Journal Article||Publisher:||Wiley||Journal:||Zeitschrift fur Angewandte Mathematik und Mechanik||Volume:||79||Start page:||S497||End page:||S498||Copyright (published version):||1999 Wiley||Keywords:||Rayleigh-Lamb waves; Crack detection; Ultrasonics||Language:||en||Status of Item:||Peer reviewed|
