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 successful development of an effective NDE technique depends on a full understanding of the physics of ultrasound interaction with the test material. This can be best achieved through numerical simulation of the wave propagation and scattering in the test material. A good numerical model can supplement the information provided by laboratory measurements on manufactured faulty bonds. Numerical models provide controllable quantitative information, subject to their own limits on accuracy, but free from the uncertainties attached to many practical ultrasonic measurements.
