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
The results presented here are part of a study of the interaction between an electro-mechanical transducer plate element and wavelengths in the test structure that are comparable to the plate dimensions. The steady time-harmonic problem is reduced to a system of singular integral equations for determining the tractions generated at the interface between the plate and half-space where a thin viscous couplant is applied. This system is solved numerically for various values of couplant viscosity and incident wavelength. Graphical results for interface tractions and reflected power are presented.
