Abstract EN
Identification of structural crack location has become an intensely investigated subject due to its practical importance.
In this paper, a hybrid method is presented to detect crack locations using wavelet transform and fractal dimension (FD) for beam structures.
Wavelet transform is employed to decompose the mode shape of the cracked beam.
In many cases, small crack location cannot be identified from approximation signal and detailed signals.
And FD estimation method is applied to calculate FD parameters of detailed signals.
The crack locations will be detected accurately by FD singularity of the detailed signals.
The effectiveness of the proposed method is validated by numerical simulations and experimental investigations for a cantilever beam.
The results indicate that the proposed method is feasible and can been extended to more complex structures.
