“…For the unworn tool, as shown in Figure 13a, the power of the AE burst waveform is distributed throughout the time span in the frequency range of 0.04-0.3 MHz. This AE frequency range is attributed to the plastic deformation of the sheet in the stamping process [15]. In Figure 13b, the maximum intensity of power distribution increases in the AE frequency range of 0.04-0.3 MHz (yellow colour in spectrogram).…”

“…The AE sampling frequency for both the tests conditions was maintained at 2 MHz per channel. To verify the contact between the AE sensors and the samples, the Hsu-Nielsen pencil lead break test was performed at the start of each test, as described in our previous studies [11,15]. ( Figure 6b).…”
