Abstract:

The present study is an extension of previously reported Nuclear Hardness Evaluation Procedures NHEP efforts. In the current study, the Failure Analysis by Statistical Techniques FAST methodology was extended to provide new techniques for estimating the potential benefits of testing under uncertainty. A new computer code named ELF, Evaluation of Likelihood Function, was developed to provide a thorough evaluation of test results. To demonstrate the ELF code, this code was used to analyze magnetic flyer plate data on graphite resin material samples. Volume 1 of the Final Report, Applications, describes the results of the evaluations performed on the graphite resin magnetic flyer plate tests and their impact on predictions of reentry system performance. Also included in Volume 1 are the results of the analyses performed on a Lockheed Missiles and Space Company reference reentry vehicle. Volume 2 of the Final Report, Methods, describes in detail the development of the statistical and analytical techniques that were incorporated into the ELF code. Also reported in this volume is a new version of the FAST code, FAST7, Conditional Probability FAST, which shows great promise for test planning and evaluation analysis.
