| Abstract | Probability of detection (PoD) studies are broadly used to provide data for damage tolerance life estimations and to determine the reliability of specific nondestructive inspection procedures. They require inspections on a large number of samples or components, a fact that makes these statistical assessments time and cost consuming. Numerical simulations could be used as a cost-effective alternative to empirical investigations for predicting the inspection outputs as a function of the inspection characteristics. The present paper focuses on the modeling aspects of eddy current testing and represents a sequel of the work formerly discussed in Part I and referring to 'Experimental Design and Data Analysis' for the bolt-hole inspection of wing box aircraft structures. A boundary-element numerical modeling software was employed to predict the eddy current signal responses when changing inspection variables related to probe, flaw, and material properties. A demonstrator exercise was used for inspection predictions in the case of lowering the eddy current testing frequency and inclusion of the simulated data in the PoD analysis. It was found that the numerical simulations have the potential to partially substitute or complement experimental data required for PoD studies, reducing the cost, time and resources required for a full experimental PoD assessment. |
