Numerical Simulation of Three Shaped Charge Jets

In order to study the single-cone liner charge,double-cone liner charge and the combination of cone and hemisphere liner charge,truegrid and the finite element software LS-DYNA are used and jet formation and penetration process on the three kinds of structure are cimulated.The results show the double-cone shaped charge has the better penetration effect,but in the big blow of high case,it is easy to break off for the jet's tail,affecting the penetration effect.
