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 model of eddy current probes with ferrite cores has been developed. The model is applicable to axisymmetric cores in the vicinity of a conducting half-space (the work piece). The model is based on modern methods of computational electromagnetics, and is intended to provide a systematic and rational basis for the design and characterization of probe coils. Eddy current responses of four probes on an aluminum workpiece were predicted by the model and compared with experimentally measured responses.
