Abstract
In recent years, there has been a growing interest in vibration-based structural health-monitoring techniques. At present, most of the vibration-based techniques consider an open crack, which is far from realistic situations. In real-life scenarios crack can open and close under the dynamic loading. This bilinear behavior of crack has a significant effect on dynamics of structures which was investigated by performing finite-element simulations of a beam with a breathing crack excited longitudinally. Its response measured at different locations with regard to the crack indicated that the crack-induced nonlinearity had a localized effect on dynamics of the beam. Measurements obtained near the crack revealed complex spectra with higher harmonics.
