Model-Based Ultrasonic NDE System Qualification Methodology
The use of computer models of ultrasonic NDE inspections is a convenient and cost-effective alternative and/or companion to experimental reliability trials used for qualifying the detection reliability of a given inspection system applied to a given inspection task. In addition, the use of such models permits qualification of ultrasonic inspection of new component designs even before such components exist. This paper presents the current status of the implementation of a model-based software package for these system qualification applications. A brief overview of the model elements and assumptions will be followed by a discussion of the detection system qualification methodology and, finally, by model-predicted qualification results with associated experimental data.
