Abstract

The method and results of diagnostics of the predestruction state are described based on deviations of the amplitude and time invariant relationships between the parameters of the flow of acoustic- emission (AE) acts and their stable values. The relationship of the AE invariant method with the methodology of the synergetic approach to the destruction of solids is shown. Amplitude invariant relationships of AE have been estimated both by tests of standard specimens of 15Kh2NMFA hull-plate steel and by the previous results of AE tests of a VVER-1000 reactor vessel.
