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
Planar cracks are the most dangerous types of flaw found in structural materials. Flat and smooth defects notify fatigue cracks or lack of root penetration. They are difficult to detect and characterize, on account of their unfavorable reflecting properties. Theoretical models of the diffraction of elastic waves have therefore an important role in the validation and development of ultrasonic Non-Destructive Testing procedures.
