Article Preview

In this paper, the continuous wavelet transform by the Gabor wavelet is applied to analyzing flexural waves in a cantilever beam with an edge crack. The amplitudes and arrival times of the incident, reflected and transmitted waves at a certain frequency are extracted from the wave signals to identify the damage location exactly and estimate the damage extent qualitatively. The results show that this is an effective damage detection method and can be extended to the damage detection of complicated structures.
