DETECTION OF CRACKS WITH CLOSURE
Vibration signatures can be used to identify the presence of fatigue cracks in steel structures and assist in locating the damage. However, the state of a crack, and in particular the degree of crack closure which depends on the loading history that caused the crack, can have a marked influence on the effect of that crack on the vibration characteristics. Experimental results are presented in this paper to show that effect on frequency and damping as a function of crack closure.
