摘要: Crack Detection on a Cantilever Beam Using the Nearest Approximation MethodFrederick A. JustVirginia Tech, Department of Engineering Science and MechanicsBlacksburg, Virginia 24060Scott L. HendricksVirginia 24060ABSTRACTThis paper deals with determination damage location magnitude evaluation by measuringthe natural frequencies structure. A uniform transverse crack, located steel cantilever prismaticbeam rectangular cross section, is used as model for damage. The crack beam assumed tobe open during transVerse vibration structure, thus effect closing opening
