Chang, H. -Y. and Petroski, H. J.. "ON DETECTING A CRACK BY TAPPING A BEAM.." International Journal of Pressure Vessels and Piping 22:1 (1986): 41 - 55. [0308-0161(86)90043-8]
Abstract:
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.
