Abstract

The complex variable method of the plane theory of elasticity was used to determine the stresses and deformations induced by gravity loads in a hollow, cylindrical, case-bonded, solid propellant rocket motor which is lying on its side. The propellant and case were assumed to be elastic, isotropic, homogeneous, and in a state of plane strain. Numerical evaluation of the series solution showed that the stresses and displacements are sensitive functions of the motor case thickness and the ratio of case and propellant moduli. The analysis further indicated that cracking of the propellant along the inside surface is more likely to occur than either case-bond failure or internal cracking of the grain. (Author)
