Integrated Quantitative Nondestructive Evaluation (NDE) and Reliability Assessment of Aging Aircraft Structures

Abstract

This report documents work performed to understand the capability and reliability of a pulsed eddy current inspection/measurement method for the detection and quantification of hidden corrosion in aircraft structures. The method has been shown to be uniquely capability of detection and quantifying corrosion in the second layer and gap thickness between layers of aircraft structure. One element of the program was the development of a first principles model of the measurement process. The model predicts both applicability and capability for application to typical aircraft structure. The model was validated by limited experimental measurements. A second major element of the project was the upgrade of analysis software for generating probability of detection analysis and plots from experimental and model generated data.
