N2 - An experimental study is reported for the location detection of a delamination in a beam structure under a static displacement with a spatial wavelet transform. An invisible perturbation in the deflection profile of the delaminated beam at the two delamination edges owing to the curvature discontinuity is discerned or amplified through a wavelet transform. In this research, two delaminated cantilever beams with different dimensions and materials subjected to a static displacement at their free ends are investigated experimentally. The static profiles of the delaminated beams acquired by a high-precision laser profile sensor are analyzed with the Gabor wavelet to identify the delamination location. Through both the finite element model (FEM) and experimental studies, the detection of the delamination location using spatial wavelet analysis is achieved effectively.
