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 shear waves are a useful tool for determining the mechanical properties of various materials. One example is the use of shear waves to measure viscosity. The viscosity can be determined from the shear wave reflection coefficient. The reflection coefficient from a solid-liquid interface is a function of the viscosity and density of the liquid, as well as the angle of incidence and the material properties of the solid. [1,2]
