Abstract

In this paper, SOM neural network was used to identify the AE signal waveforms of aircraft fatigue test, which produced a group of suspected crack signals. Three peaks of relatively large energy appear simultaneously in frequency spectra. The frequency of peak 3 (168.5 kHz) was consistent with previous result (175.8 kHz), showing characteristics of crack AE signal. [ABSTRACT FROM AUTHOR]
