Acoustic Emissions & Acoustic Condition Monitoring
Acoustic Emission: AE is used for effectively monitoring different machine conditions; balanced, unbalanced, misaligned and defecting bearings. Monitoring equipment using AE works on the principle of using transient elastic waves to detect the rapid release of strain energy caused by deformations or damage within the surface of materials.
Real-time Acoustic Emission Classification: New
2012-10-9 real-time applications. On the other hand, Acoustic Emission is a non-destructive test (NDT) technique that bases its success on the real-time monitoring capability. This lack of algorithms able to integrate directly into the AE acquisition/processing chain has motivate this work. Inspired by sequential k-means, i.e, a non-iterative variant

An Acoustic Emission Data-Driven Model to Simulate
2019-11-15 Numerical simulation is a commonly used method for investigating rock failure. However, the numerical model is usually insufficient to predict real rock damage and failure because of rock microstructural heterogeneity. In fact, rock damage can be quantified using acoustic emission (AE) data. The aim of this study is to simulate and predict the failure of Brazilian and uniaxial compression
