Discrimination of Acoustic Emission Events Based on Similarity of Describing Parameters

Popis výsledku v původním jazyce

This paper describes a new method developed for the discrimination of acoustic emission (AE) events based on the similarity of their parameters. The method should help to locate the sources of AE events which are related to failure of the material's integrity. Early detection of crack growth is critical for the prevention of catastrophic failure. The problem is that during long-term monitoring of construction, many AE events captured are disturbances. If standard methods of discrimination are used, a number of clusters of AE events are located. The developed method uses the specific behavior of AE sources generated by the crack propagation in the material to discriminate between those sources and the disturbances. The discrimination is based on the similarity of AE parameters. The proposed method was validated on real data from measurements of two different chemical reactors. The reference data were obtained by ultrasonic inspection after dismantling the objects.
