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 sensor which measures physical parameters of a liquid with high sensitivity and accuracy is in great demand in medicine, biology, chemistry and environmental science [1]. Recently, resurgent interest in Lamb waves was initiated in their applications of multisensors [2]. The principle of these Lamb-Wave Sensors is that the propagation velocity of Lamb waves changes when a plate is bordered with a liquid. In this paper, we report the results of our recent theoretical investigations of the effects of bordering liquid layers on the propagation of Lamb waves in a solid plate.
