Crack detection in beams using kurtosis

A new technique for crack detection in beam structures based on kurtosis is presented. The fundamental vibration mode of the cracked cantilever beam is analyzed and both the location and size of the crack are estimated. The location of the crack is determined by the abrupt changes in the spatial var...
