Abstract:

This report presents a detailed analysis of the loading conditions to which the 5-in.54 HI-FRAG Projectile is subjected. These loading conditions include the following press fit, gun ramming or rebound upon exit from the barrel. The analyses are based on finite element, analytical, and experimental results. Were applicable, various results are correlated to show their validity. The analyses show that the joint region is the most highly stressed region in the projectile. The critical flaw size under 18,000 gs gunlaunch loading conditions is about 0.028 by 0.28 inches for a sharp elliptical crack in the joint region at 0.006 inches radial interference.
