Identification of Crack Location in Beam Structures Using Wavelet Transform and Fractal Dimension

Figure 5

Crack location identification results in 80 dB noise level for the first mode shape. (a) Noise contaminated the first mode shape SN and its wavelet decomposition at level 2. (b) FD of the detailed signal .
