METROLOGICAL ASPECTS OF THE PROCESS OF RECORDING THE ENERGY PARAMETERS OF THE ACOUSTIC EMISSION OF SUBSTANCES

摘要

The basic problems of the acoustic-emission method of nondestructive testing are analyzed. Comparative estimation of the effectiveness of the parameters of acoustic emission signals is performed. It is demonstrated that the methods of analysis are inadequate in a narrow frequency band. The need for the use of methods of spectral analysis for the purpose of increasing the precision and reliability of results is demonstrated.
