Simulation Study on Metamorphic Tapered Angle Shaped Charge under Underwater Explosion

2012 
For improving the damage effect to underwater target of warhead,a kind of metamorphic tapered angle shaped charge is designed,and the damage mechanism is analyzed.The physics model of tapered and spherical shaped charge under underwater explosion is build,numerical simulation is done by LS—DYNA,and the stress distribution is got.The result shows that the shaped charge jet formed by this structure can provide movement space for latter EFP,which improving the damage effect to target.
