FIELD: physics.
SUBSTANCE: invention can be used for monitoring of kinetics of viscous and brittle damages in structure of structural material with application of acoustic emission diagnostics. Essence of the invention consists in the fact that based on the combined analysis of the amplitude decay steepness at the attenuation phase of the signal with spectrograms, the recorded AE signals are divided into flows generated by viscous and fragile damages of the material structure.
EFFECT: enabling monitoring of partial content of viscous and brittle damage accumulation in the article loading mode.
