Closure Effects on Fatigue Crack Detection
Publication: Journal of Engineering Mechanics
Volume 125, Issue 10
Abstract
An experimental study of crack closure and its effects on the vibration of a simple beam shows that both frequency and damping changes due to the crack are influenced significantly, to the point of being obscured in some cases. The nonlinearity induced by crack closure is also explored. The results will be of value in the further development of models to detect crack damage in structures as well as in modeling crack closure and the mechanism of damping at a crack.
