Description

Much of the interest in using acoustic emission to monitor structural components is a result of the ability of the technique to detect growing cracks. The greatest problem standing in the way of applying this technique is the presence of signals from innocuous sources, which can make identification of crack-produced emission difficult, especially in those circumstances when cracks must be detected in real time and without other reliable correlation parameters. The test results presented here suggest an approach to eliminate spurious signals from acoustic emission data, which may be applicable to real time analysis and amenable to a variety-of monitoring methods.

Application of Pattern Recognition Techniques to Acoustic Emission from Steel and Aluminum
