Evaluation of NDE Reliability Characterization. Volume I

Abstract

To characterize the uncertainty in non-destructive evaluation (NDE), a probability of crack detection (POD) as a function of crack length is postulated where POD is defined as the proportion of cracks of a given length that would be detected by the NDE technique when applied by inspectors to structural elements in a defined environment. This report; (1) presents a statistical framework for describing the uncertainty in the NDE determinations; and (2) evaluated various characterizations of NDE reliability. The data from a recent Air Force study on NDE reliability estimate the parameters of the NDE model. For these representative capabilities NDE reliability experiments are simulated. Different NDE capability characterizations are computed for each simulated experiment and are statistically compared. (Author)
