STATISTICAL STUDY OF ECT DETECTION AROUND FASTENERS USING SIMULATION BASED POD CURVES

Calculation of Probability of Detection (POD) curves based on simulation results are presented in the case of the Eddy Current Testing (ECT) configurations involving a flaw buried inside a riveted structure. In order to overcome some accuracy limitations and to optimize calculation speed, the semi‐analytical model used in simulation has been improved in order to handle separate discretizations of objects. New possibilities consecutive to this development are presented, as well as two parametric models used for the computation of interactive POD curves with the CIVA software.
