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
In studies of ultrasonic measurements of interfacial properties, it has previously been proposed [1] that an ultrasonic wave that produces shear stress on the interphase is sensitive to interphase properties. This may be achieved by utilization of interface waves [1,2] or guided waves in the bonded plates [3–5]. Another possibility is the use of obliquely incident ultrasonic waves for interphase evaluation, analyzing signals in the time or frequency domains [6–8].
