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 development of acoustoelasticity as a tool for the nondestructive evaluation of active and residual stresses, it has become clear that the anisotropy of the materials under examination plays a significant role in the ultimate utility of the method [1, 2]. This technique is based on the observation that the speeds at which various waves propagate through a material depend not only on the elastic stiffness, but also on the amount of deformation or stress to which the material is subjected. If a material’s elastic and acoustoelastic constants are known, and if sufficiently precise measurements of velocity are made, the stress may be evaluated.
