Simulation Study on Tapered and Spherical Shaped Charge under Underwater Explosion

摘要：

For improving the damage effect to underwater target of warhead, a kind of metamorphic tapered angle shaped charge is designed, and the damge mechanism is analyzed. The physics modle of tapered and spherical shaped charge under underwater explosion is built, numerical simulation is done by LS-DYNA, the stress distribution and velocity of jet are got. The result shows that the shaped charge jet formed by this kind of structure can provide moving space for latter EFP, which improving the damage effect to target.
