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

Current designs for large light-weight space structures prompt the need for enhanced damping of the structural system to improve system performance and/or simplify the controls designs. Enhancement of passive damping with local active damping is very desirable. Development of embedded sensors, actuators, and signal processing systems would provide local control superior to passive damping techniques.
