Diagnostic Acoustic Emission technological concept
DiagnosticAE is a technological concept that is used for development of acoustic emission technologies for examination, diagnostics and monitoring of different structures. A technology developed within the frame of this concept is called DiagnosticAE technology. The DiagnosticAE concept combines methods of non-destructive testing, structural health monitoring and predictive maintenance. It provides necessary considerations for effective development of new AE applications, practical field testing, approaches for data analysis and results interpretation. DiagnosticAE concept complies with the best standard practices existing in the field of AE but at the same time brings new qualities to acoustic emission testing, provides more comprehensive results, increase success of AE examination. Formally defined:
DiagnosticAE is an acoustic emission technology capable to achieve goals of AE diagnosis: detection, identification and assessment of flaws, properties or conditions that affect or may affect in future safety/performance of a structure.
Related definitions:
- AE diagnosis is a process of detection, identification and assessment of flaws, properties or conditions that affect or may affect in future safety/performance of a structure by the acoustic emission method.
- Structural health monitoring is a process of diagnosis and monitoring condition of structures normally performed during their operation.
- Flaw – an imperfection or discontinuity that may be detectable by nondestructive testing and is not necessarily rejectable.
- Fault – an abnormal condition or defect at the component, equipment, or sub-system level which may lead to a failure.
- Monitoring – a process of follow-up over changes in the condition of a structure.
- Prediction – a process of estimation of possible future flaw/fault deterioration based on results of diagnostics, monitoring and/or numerical modeling.
