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

Computer simulation techniques are continuously expanding their role as basic tools in fields, such as Quantitative Non Destructive Evaluation, in which it is important to gain a good understanding of the propagation mechanisms of waves or pulses in complex media. A method, which has been designed for the above purpose and is particularly efficient, especially if applied in conjunction with parallel processing, is the Local Interaction Simulation Approach (LISA)[l–3]. As spin-offs of LISA, the Sharp Interface Model (SIM)[4] and the Spring Model have overcome [5] the difficulties encountered in treating sharp or imperfect contact interfaces by means of the usual Finite Difference (FD) techniques.
