AE source location can be performed in several ways, including the linear, zonal, and triangulation methods, depending on the structural geometry and accuracy requirement. For a linear structure, the linear location method is sufficient. For 2D geometry, which is not necessarily flat, the zonal and triangulation methods are suitable solutions. The former gives a zone location based on what channels detected the AE event, and the latter gives a point location based on the times arrived at three or more sensors.
Obviously the models have to be updated each time to ensure that the simulations mimic the field response. This also enables the prediction of potential ‘hot spots’ in the structure providing a means of identifying where, and when, maintenance is needed. The integration of analysis tools that account for variability due to variation in materials, and the time- and environment-based deterioration thereof, would also be essential if a true assessment is to be made. e. not just being able to state that the ‘patient’ is sick, but rather of being able to pinpoint the location and reason, as well as the effect of the incapacity.
The AE technique offers some unique capabilities such as: • • • • • real-time detection; continuous monitoring; rapid and global inspection; suitable for remote and unattended NDE operations; can be used at any stage of a composite structure lifespan from manufacturing to service. 12 © Woodhead Publishing Limited, 2013 28 Non-destructive evaluation (NDE) of polymer matrix composites In addition, AE has also exhibited some superior capabilities in detecting certain types of damage: • Because the AE method detects the damage as it occurs, it is more effective in detecting damages that cause no apparent deformation, such as delamination or cracks along the fiber direction in thick composites or tapered composite sections.
