24.3.2 Acoustic Emission Single Waveform and Spectrum
Characteristics
The acoustic emission single waveforms and spectrum diagrams of different stages
of the three samples during the tensile process were analyzed.
The frequency distribution of the acoustic emission single of the three sensors of
the A sample is shown in Table 24.4, and the different stages are shown in Fig. 24.10c;
the frequency distribution of the acoustic emission signals of the three sensors of the
Sample B are shown in Table 24.5, and the stages are shown in Fig. 24.11c; the
