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

A recently-developed model allows the prediction of echo-responses from targets of various geometry and acoustic impedance [1,2]. The model is briefly reviewed then used to predict echo-responses from angled planar targets, these results being compared with experimental measurements. This comparison allows the definition of its domain of applicability. Implications for QNDE are discussed. Particular attention is given to the physical interpretation of the results in term of scattering of the geometrical and edge wave components of the incident field.
