This paper addresses the problem of identifying structural damage a!ecting one zone of a beam using measured frequencies. The beam model has a zone in which the sti!ness is lower than the undamaged value. Damage is de"ned by three parameters: position, extension and degree, which need to be identi"e

Numerical and experimental studies for crack detection in beam employing transverse impact are presented. In the numerical study, a beam model of wave propagation is developed to calculate the time history of beam response before, over and after the crack region. It is expected that the resulting wa
