| Abstract: | Dispersion and attenuation characteristics of stress waves were studied by means of the automatic data collection and FFT technique. Test results of alluminium were compared with the theoretical results to verify the reliabitity of the methods adopted. Based on our experiments, several problems on the test technique of stress waves and data treatment were studied. |
