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

The objective of the ongoing work reported here is to optimize pulsed eddy current instrumentation for the detection of small flaws, specifically 250 × 125 pm crack-like defects in low conductivity materials such as titanium 6-4. Our approach parallels that employed in the optimization of continuous wave eddy current systems1,2 in that we seek first to develop a mathematical model of a typical flaw detection system, and then use the model as a guide in the design of probe instrumentation and in the selection of signal processing methods to enhance flaw detectability.
