This paper presents a new method for identifying the characteristics of acoustic emission (AE) source employing Artificial Neural Network (ANN). The three stages of flaw's development, formation, diffusion, rupture, are taken as the AE source. Sample the AE signal. Analyse its wave form and accomplish the pattern recognition by using ANN. This method can be used to determine if the flaw will go on to diffuse or rupture. It can also be used to distinct different AE signals sent out from different AE sources such as noise, leakage and flaw, etc.
