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 space station is an internally pressurized container carrying inside it everything necessary to support human life in space. Since the shell of the space station contains numerous penetrations it will always be susceptible to seal failure, and when in orbit it will also be exposed to impacts from meteoroids and debris. Although designed to minimize the effects of impacts, damage which breaches the shell threatens the lives of the astronauts. Even small penetrations may require an unacceptable amount of time and effort to locate if a manual scan is necessary. Monitoring under these conditions is best done with acoustic emission (AE), which can be configured as a continuous, remote, and operator-independent monitoring system capable of detecting and locating large and small damage sources.
