Abstract : A series of computer programs based on finite element methods has been developed for the stress analysis of solid propellant rocket grains and similar geometric configurations. These programs have the capability of analyzing (1) a linear elastic, isotropic, axisymmetrically loaded, axisymmetric propellant grain with (or without) an orthotropic elastic motor case, (2) a linear elastic, isotropic, plane section with (or without) an orthotropic case, or (3) an axisymmetric, orthotropic shell. Loadings of arbitrarily varying pressure, body force, and thermal gradients are allowable. Extensive data generation and data output features are included in the programs to reduce both errors and effort involved in data preparation and data reduction. (Author)
