Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

The need to quantify and predict the probability of detection (POD) of defects by ultrasonic nondestructive evaluation (NDE) techniques is driven by the growing importance of damage tolerant design and maintenance philosophies. Experimental demonstration programs, while costly, are useful in assessing NDE system reliability for existent inspection hardware and for “typical” test specimens. However, such an approach is not effective for prediction of optimal inspection protocols nor for improving the inspectability of components at the design stage. There is, thus, a need for computationally efficient analytical models for such applications.
