Fundamental Studies Relating to Systems Analysis of Solid Propellants

Abstract

The earlier progress reports presented some essentials of model representation and a summary of some elastic solutions as preliminary material for viscoelastic analyses of solid propellants under various loading conditions. The present report is a continuation of the above with a brief section on Thermal Distributions, a section called Engineering Analysis, and one on Failure Criteria. The thermal distributions, obtained from heat transfer theory, are required for the thermoelastic formulations of section II. The Engineering Analysis section includes several varied examples to assist in understanding the analysis techniques presented in the other sections. The final section relates to mechanical failure of propellants and presents some preliminary thoughts as to how the study of this important problem area will be conducted.
