Three Dimensional Stress Analysis of an Artillery Projectile Joint

Abstract

This study presents the results of a three-dimensional elastic plastic dynamic stress analysis of one of the structural joints encountered in artillery projectiles. The particular spline joint analyzed has equally spaced set screws around the surface of the projectile. In general, these types of structural joint problems are variable contact problems in that the interaction between the set screws and their bearing surface along with the interaction between the interfaces of the joint are nonlinear in nature. Due to the complexity of the structural configuration and loading of the joint, the finite element method has been used to solve the problem. The numerical analysis covers the time from initial launching to barrel exit. Stresses and deformations in the joint are determined at various stages of loading. The effect of the set screw holes on the stress distributions in the joint is examined in detail.
