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
In circumstances where multi-layered structures play a critical role in the performance of manufactured components, a thorough and detailed inspection procedure is required. However the construction of such objects is such that it is not easy to provide an adequate non-destructive test to monitor the state of the structure. It is possible to employ x-ray techniques, but on these layered (or cylindrically symmetric) structures many exposures are required over a range of positions, which is both expensive and time consuming. It is therefore attractive to use an ultrasonic NDT system. A further important motivation for using ultrasound is its sensitivity to a large number of material parameters.
