MODEL‐ASSISTED PROBABILITY OF DETECTION EVALUATION FOR EDDY CURRENT INSPECTION OF FASTENER SITES

A model‐assisted approach for the design and execution of probability of detection (POD) studies is proposed. General agreement was achieved between experimental and full‐model assisted results for eddy current inspection of cracks at fastener sites located at both the first and second layers. The accuracy of the POD results was found to be dependent upon the NDE model and assumptions in the model‐assisted POD evaluation. Insight is presented for improving the quality of future studies.
