The application of matlab in bolt bonding integrity non-destructive testing

Signal processing is an important component of bolt bonding integrity non-destructive testing. The wavelet analysis is one important component of the matlab software which function is a very powerful. Wavelet analysis as an effective tool used for the characteristics analysis of the signal was more in-detail analysis compared with Fourier analysis. Wavelet analysis applied in the bolt bonding integrity non-destructive testing, that can detect signal with time-frequency local treatment and get the characteristics associated with the bolt bond state.
