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
A computer simulation of nondestructive failure prediction in silicon nitride containing silicon inclusions has been developed. The preliminary application of the simulation examines the results of an inspection that uses a single transducer in the pitch/catch mode. The limitations of the inspection method, especially when applied to nonspherical inclusions, are exposed by the simulation. Also the expected influences of the signal-to-noise ratio and the inclusion size distribution on the fail~re and rejection probabilities emerge from the analysis in quantitative form.
