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

Advanced design of aircraft structures may incorporate areas inaccessible for in-service inspection. It is important to monitor high stress intensity substructures on aircraft to assure the integrity of aircraft structures and to decrease life-cycle cost of advanced military aircraft. Acoustic emission (AE) provides an ideal means for real-time structural monitoring. Acoustic emission is the stress wave generated by rapid release of energy from localized sources within a stressed material. Acoustic sensors combined with an effective signal processor can be used to detect acoustic emission events related to structural damages and serve as a real-time nondestructive evaluation (NDE) tool.
