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 work reported here is part of a program on flaw detection in turbine rotor components. The goal is to image or map non-surface breaking fatigue cracks near the bore hole surface of an aircraft engine disk with the aid of ultrasonic inversion techniques. Presented are results of inversion of both pitchcatch and pulse-echo data with the inversion technique discussed in detail in the companion paper
