notch sample (C)
circular notch segment 8 × 17 × 2.2 mm, C is the preset V-shaped notch sample,
and the deformable part is 2 × 2 × 2.2 mm of V-shaped connecting segment.
The acoustic emission detector use the AMSY6 acoustic emission detection
system of Vallen Company in Germany. It uses two VS150-M resonant sensors with
a peak response frequency of 150 kHz (operating frequency range of 100–450 kHz)
and one VS45-H broadband sensor (operating frequency range of 20–450 kHz), a
VS900-M wideband sensor (working range 100–900 kHz) collects the signal, and
the signal is amplified by a preamplifier with a 20–1000 kHz band-pass filter, the gain
