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

In our previous work [1,2,3,], we have studied in detail the radial-axial modes in an infinitely clad isotropic rod. We have shown that in metal matrix composites, where the fibers are stiffer than the matrix, many of these modes are leaky, transmitting energy into the surrounding medium. The existence of this leakage energy offers a potential means for monitoring and imaging the characteristics of the interface zone [2,3,4,]. Detailed numerical methods have been developed for analyzing radial-axial leaky modes in composite systems [1]. The present paper shows an example of these methods applied to determining the sensitivity of the maximum phase velocity to the matrix density changes for leaky modes.
