Summary on Grant Application Form
The use of acoustic emission (AE) testing techniques in industry has grown rapidly in recent years. There are several major suppliers of general purpose industrial AE equipment, and other companies are successfully operating their own AE systems tailored to their specific applications, such as the Airbus BALRUE system. The purpose of this project is to provide quantitative scientific underpinning for the application of modern AE techniques in industrial situations. A key goal of the project is to develop a physical model of the complete AE process from source to detection. This will use guided wave techniques to model both the excitation and propagation of AE signals through real structures. The model will be used to provide quantitative assessment of the suitability of AE for different applications, optimise AE configurations and as a benchmarking tool for new AE signal processing algorithms. By using a deterministic physical model rather than a probabilistic empirical approach, the project will seek to increase confidence in the AE technique and allow it to be integrated into the wider quantitative non-destructive evaluation (NDE) toolbox. For this purpose, the project will also define objective measures of AE capability that are comparable to those used for other NDE techniques, such as probability of detection and false call probability. Finally the project will investigate the possibility of applying recently developed guided wave signal processing techniques to enhance the performance of the AE testing process.
