| Abstract |
Concern about premature explosions in artillery shells has increased with the advent of high-performance ballistic characteristics and the use of composition-B as the high-explosive fill. An effort in expanding the state of the art in artillery shell structural dynamics and its effects on premature explosions is described. Results are presented of calculations on the macroscopic state of stress and motion in various artillery projectiles, including the M437 (175 mm), M549 (155 mm), M107 (155 mm), and M795 (155 mm). The effect of conditions at the high explosive-steel case interface (unbonded and bonded) were examined to determine the gains derivable from bonding this interface. These dynamic simulations included a detailed examination of the effects of Coulomb friction for both normal and abnormal loading conditions. Also, the effects of erratic propellant burns, environmental conditioning, and various aspects of gun launch loads are presented. It is shown that structural response is strongly affected by whether or not the projectile has a rocket-assisted configuration. (ERA citation 08:024217) |
