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 the course of processing and use of modern composites it is desireable to be able to determine estimates of their elastic properties. Elastic property information available during processing could be used to determine the state of cure of a composite. This would make possible feedback control of the cure process, thus helping to insure uniform materials. Knowledge of the elastic properties over time of in-use structures such as aircraft, marine, and rocket motor components would also allow quantitative health monitoring of these critical devices.
