Acoustic Emission Testing
Original language description
Acoustic Emission (AE) is a non-destructive method in that aims to do a wide group of analysis to examine the behaviour and evaluate the properties of a material deforming under stress without causing any damage. The defectoscopy principle is used to characterize and identify the damage developments. Reliable identification and classification of pre-localized AE sources is one of the most important and also most difficult problems in AE monitoring. In order to classify different AE sources, suitable signal parameters and a classification method are necessary. In this work, the signals are distinguished by means of newly suggested parameters obtained directly from signals and from signal spectra. The parameters are calculated from a continuous version of formerly suggested successful parameters. As the classification method k-means and the Gaussian Mixture Model (GMM) are used. All suggested parameters along with the classification method are tested on the laboratory measured different
