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

Eddy current testing is currently used to determine conductive specimen physical characteristics and to detect defects by measurements of electrical impedance of an eddy current probe. In general, reliable quantitative NDE requires accurate measurements and a theory to interpret them. In some NDE applications related to coated metals inspection eddy current probes which induce planar or linear currents in a sample are used for flaw detection, thickness and conductivity measurements [1]. For probes of this type, e.g. rectangular or meander like coils, there still exists the need of theoretical modeling.
