MODELING CRACK CLOSURE EFFECTS ON FREQUENCY AND DAMPING
Abstract eng: Because vibration signatures can be used to identify the presence of fatigue cracks and assist in locating damage, it is important to understand how cracks affect modal frequencies and damping. Experimental results are presented here to show how the effect of a crack depends on the crack history and the degree of crack closure. Nonlinear effects are demonstrated. Modeling of the mechanism by which the crack interfaces affect frequency and damping is outlined.
