Contribution of functional approach to the classification and the identification of acoustic emission source mechanisms
Résumé
In a context of nuclear Reactivity Initiated Accident, we describe acoustic emission signals, for which a problem of classification is open. As classical approaches with a reduced number of variables do not give satisfactory discrimination, we propose to use the envelopes of the received signals.We perform a k-means clustering and discuss the first results of this approach.
