title = "A model-based probability of detection approach to refinement of Eddy current inspection of condenser tubes",
abstract = "The Navy has been interested in moving from a time-based approach to nondestructive inspection of condenser tubes to a condition-based approach in order to support the increased availability of our military assets. The accuracy and precision with which discontinuities can be identified by nondestructive examination (NDE) methods is a critical issue for the successful application of condition-based maintenance to aging military platforms. Probability of detection (POD) studies are one means by which to determine the reliability of a given nondestructive inspection method for a specific application; however, there are underlying costs associated with performing conventional POD studies that often become prohibitive. Modeling is seen as a potential means by which variables can be studied within the eddy current inspection process, without the expense associated with extensive experimental work. We have made use of VIC-3D, a commercial-off-the-self software package developed by Victor Technologies, to model calibration standards used in eddy current condenser tube inspection. The unknown probe parameters have been estimated by matching the modeling results to the experimental results. The effect of cables attached to the probe has been added to the idealized responses of the model output. As an example of the potential application of our approach, we show POD to depend on the choice of the measured response function and the detection threshold, where the frequency is considered to be the only variable following normal statistics in the measurement process.",
