| Abstract: | The wavelet transform (WT) is applied to the time-frequency analysis of flexural waves in beams. The WT with the Gabor wavelet
decomposes a dispersive wave into each frequency component in the time domain, which enables one to determine the traveling
time of a wave along the beam at each frequency. By utilizing this fact, a method is developed to identify the dispersion
relation and impact site of beams. |
