Abstract
In designing large booster structures, a major area requiring extensive stress analysis is the discontinuous region, such as the skirt intersection, the sculptured joint, and the reinforced opening.
This paper presents a computer solution of stresses and displacement in a typical skirt intersection consisting of (1) a variable-walled transition cylinder, (2) a skirt cylinder, (3) a spheroidal dome, and (4) an infinitely long cylinder. The solution of the variable-walled cylinder is accomplished by integrating numerically a fourth-order differential equation.
From the computer analysis the theoretical stresses at the intersection of a typical large-diameter rocket motor case are obtained.
