FIELD: physics.
SUBSTANCE: in compliance with proposed method, the material specimen if loaded with the help of hydraulic press to register the acoustic signal emission. Said specimen is subjected to pulse effects to produce a longitudinal elastic wave. The latter stimulates a massive synchronous escape of dislocations from material crystal to get a total signal of acoustic emission recorded by piezo-transducer in a stable way.
EFFECT: simplified registration and processing of acoustic emission signal.
