Abstract
The objective of this work was to demonstrate the application of eddy current modeling to the determination of the probability of crack detection. The method of calculation, derived from previously reported work on the boundary element method (BEM) [1], used concepts discussed in other works on probability of detection (POD) calculations [2,3]. In contrast to the earlier POD investigations, which were concerned with crack-like flaws in flat plates with a simple circular coil as the probe, the present modeling deals with a realistic part geometry and a split-D probe configuration with ferrite cores and shield. Figures 1 and 2 show the part and probe geometries, respectively; the specifics of the inspection problem are described in the first section of this paper.
