Abstract(in English) | It performs imaging of the damage as damage exploration techniques using Lamb waves. Because higher resolution is required in an imaging techniques, in this study examine analysis by Wigner-Ville distribution which has very high resolution as a time-frequency analysis method of the signal. After comparing it with the Wavelet transform that is a conventional method, it confirmed improvement of the resolution and showed effective possibility as a signal analysis technique in the imaging of the damage. |
