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

There are many methods to measure the properties of composite materials. For instance, the elastic constants of orthotropic composite materials can be identified from the measurement of waves velocities by cutting the samples in various directions to access to all constants [1]. These destructive measurements are not available when the purpose is to follow the evolution of materials after or during the exposure of a damage (stress, corrosion, temperature ...). Composite materials are often made of the plies superposition in the shape of thin plates [2]. So, the well-known immersion method [ 3,4,5, 6 ... ] is very well adapted to the non-destructive evaluation of plate shaped, orthotropic materials.
