Effects of the Gridding to Numerical Simulation of the Armour-Piercing Warhead Penetration through the Steel Target

Abstract

paper studies the influencing rule of gridding definition forcalculating resultin numerical simulation of the armour-piercing warhead penetration through the steel target, so we can get the reasonable scope of grid size. Paper has used the adopted explicit dynamic analyzing program AUTODYN to simulate the process of the armour-piercing penetration through the steel target. Based on the simulation, we get the penetration deepness,penetration overload and damage area of the target in conditions of different gridsize. In order to get more reasonableresult, the scope ofgridsizeis equaled to about 5.0mm by contradistinguishing and analyzing.
