Acoustic Emission Source Localization in Plate-Like Structure

This article proposes a geometric approach for acoustic emission source (AE) localization in plate-like structure. In order to determine the arrival time of the acoustic emission waves for each sensor with more precision, we have used two techniques, the first one is based on thresholding and the second is based on the continuous wavelet transform. Experimental test have been carried out on steel plate shown that the continuous wavelet transform allows to improve the accuracy of the acoustic emission source localization.
