Abstract

Classification of acoustic emission (AE) sources during industrial object control is one of the most important and principle technological operations of acoustic method. The basic estimation criteria of acoustic emission sources are considered. Results of experimental data analysis show compliance with estimated criteria at repeated acoustic stressing; also the intensity results of acoustic emission impulses at the full test are given.

Keywords: acoustic emission, the stressing schedule, criteria of acoustic emission, pressure, converters (gauges) of acoustic emission
