Paper Title:
Mechanical Behavior of the Long Rod Penetrator during Launch
  Abstract

This study presents a three-dimensional dynamic stress analysis of the sabot/rod system during launch. A study was undertaken to investigate the influence of forward sabot diameter and rod length on the stress of projectile rod traveling in the gun tube. Three types of gun tube profile were simulated. The first profile is straight. The second profile of the tube droop is caused only by gravity and the third is combined droop profile which is caused by gravity with the manufacture status. Numerical simulation results showed that the maximum von Mises stress due to in-bore behavior of the sabot/rod system could be decreased by changing the forward sabot diameter in a tube drooped by gravity loads with the manufacture status. The results also showed that the stress of rod was affected by the factor of at·L/D· ( at ; combined acceleration, L ; length of rod, D ; diameter of rod), and it becomes minimum when the aspect ratio L/D becomes 14 in the model used in the study. in the study
