Structural Computer Code Evaluation. Volume I

Abstract

This report summarizes the first phase of a study of nonlinear structural analysis computer codes for rocket nozzle stress analysis. A brief summary of nonlinear structural mechanics is given, along with a discussion of features desired for rocket nozzle thermomechanical stress analysis. Several computer codes are evaluated, and four codes are selected for further study in a subsequent phase of this work. Two of the selected codes employed linear elastic material behavior, while the remaining codes employed fully nonlinear behavior. The codes selected for this study were SAAS III, TEXGAP, NONSAP, and NEPSAP. It should be noted that none of the codes selected for this study contained all of the features desired for structural analysis of modern rocket nozzles; however, it is anticipated that future versions of these codes will contain the desired features.
