Abstract:Abstract. Identifying non-uniform cracks in plates is a challenging problem worthy of exploration. 2D modal curvature is often utilized to detect damage in plates, but its capability to precisely identify non-uniform cracks has not been resolved well, largely due to two noticeable deficiencies, lack of sensitivity to damage and susceptibility to noise interference. With this concern, this study ameliorates the 2D modal curvature using the wavelet transform, whereby the wavelet 2D modal curvature is constructed… Show more
