Abstract

This paper describes the difficulties and solutions achieved in applying advanced Acoustic Emission (AE) signal analysis techniques to fracture mechanics. The test specimen is a double cantilever beam cut from a block of Charcoal granite. Crack growth is initiated at a Chevron notch in the specimen. Also described is a CAMAC (Computer Automated Measurement and Control) based data acquisition system. This system can capture and transfer AE event time histories at least 10 times faster than traditional oscilloscopes. An inexpensive personal computer is used for system control and storage.
