On detecting a crack by tapping a beam


Journal Article

A simple model for the cracked elastic beam is employed to simulate its response to a sharp tap at an arbitrary location. Explicit expressions for the Fourier components of the response of a simply-supported beam make it possible to explore various strategies for detecting the crack via signature analysis and to provide rational explanations for some characteristic responses of cracked beams. © 1986.
