Empirical Approach to Defect Detection Probability by Acoustic Emission Testing

Abstract: Estimation of probability of defect detection (POD) is one of the most important problems in acoustic emission (AE) testing. It is caused by the influence of the material microstructure parameters on the diagnostic data, variability of noises, the ambiguous assessment of the materials emissivity, and other factors, which hamper modeling the AE data, as well as the a priori determination of the diagnostic parameters necessary for calculating POD. In this study, we propose an empirical approach based on the gene… Show more

“…This was rather coarse for accurate measurements, but was enough for navigating a fine tool with higher accuracy to the area of the crack for detailed metrological inspection. To identify the moment T AE of crack appearance, the threshold criterion [ 41 ] was applied. For each new AE event, we evaluated its position and updated the location histogram.…”

“…It enables regular equipment inspections and online monitoring. AE technology is increasingly recognized as an irreplaceable research method and testing means in certain domains (Prokop'ev et al, 2023;Banerjee and Mukherjee, 2023;Barat et al, 2021;Sohaib et al, 2019).…”
