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
One of the major concerns in nondestructive evaluation (NDE) is the detection and characterization of cracks in structural materials. In the development of NDE methodologies, laboratory samples containing known flaws are very useful for the experimental verification of models and algorithms. Simulated flaws made to specific design serve to check the correctness of various aspects of an NDE technique under development. In addition, model flaws are also used in the calibration of nondestructive testing equipments. A familiar example is the ubiquitous flat bottom hole test blocks.
