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 nondestructive measurement of stress is a continuing concern to the railroad industry. Severe web cracking tendencies in some rails have been linked to high residual stresses created during rail production. Rails are plastically deformed during the final stage of production, known as roller-straightening. While most rails have the same characteristic stress distribution afforded by this process, safety concerns warrant the detection of pronounced stress levels that would lead to exaggerated cracking behavior.
