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

Nondestructive testing is a vital tool in the effort to ensure the quality of mechanically highly-loaded aero-engine parts. Nondestructive testing methods, such as eddy current and dye penetrant, are used to verify the surface condition of components, this condition greatly affecting operational safety and service life. Yet while these methods will readily detect small cracks, they fail to show the gradual changes in surface topology commonly associated with service wear.
