Crack Identification in Plates Using Fractal Dimension Analysis

Abstract:

Focusing on the damage detection using the fractal dimension analysis in plates, this study begins by giving a fractal dimension scanning method for beams. Then extend the algorithm to the plates by degrading the plate mode shape into transverse and longitudinal directions. With the affine transformation, the proposed method overcomes the incapability of identifying damage when using the higher-order mode shapes of the existing fractal dimension methods. Numerical results show that different types of cracks, crack locations and lengths can be detected using this method.
