Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

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

Ultrasonic transmission through a moderately curved fluid-solid interface is a problem of obvious practical interest to QNDE. Extreme surface curvatures result in an erratic transmitted beam geometry ill-suited for a measurement probe. However, in many (if not the majority) of cases, a component surface has a moderate machined or cast curvature which distorts the beam in a well-behaved manner, making the prospect of an ultrasonic inspection viable. The quantitative utility of such an inspection will depend on the ability to model this beam distortion.
