APPLICATION OF MODEL‐ASSISTED POD USING A TRANSFER FUNCTION APPROACH

A transfer function approach to model‐assisted probability of detection (POD) has been applied to the detection of fatigue cracks at fastener holes. The model uses data obtained from field trials and laboratory experiments and takes into account the effects of structural geometry, the natural variability in fatigue cracks and human factors in the inspection process. A fully representative POD trial was not feasible for this inspection procedure, and so this application provides an important real‐world context for the development of model‐assisted POD.
