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
Considerable attention has been given recently to techniques for predicting stress and texture from the angular dependence of the velocity of guided ultrasonic modes in plates [1–4]. The analysis on which the measurements are interpreted is based on the continuum theory of elasticity. No influence of stress induced dislocation motion on the velocity is considered and plastic deformation only enters the theory through the changes in texture sensitive elastic constants, induced by such processes as grain rotation.
