Numerical Simulation on Jet Formation and Projectile into Concrete Target of a New Star Shaped Liner

In order to improve the destructive power of the structure of forward shaped charge and explosion-proof body for tandem warhead on concrete medium,the LS-DYNA was used to perform numerical simulation on the process that a structure of the new star shaped liner forms jet penetrating concrete target in order to analyze the forming process whereof and the penetrating result on the concrete target.Comparing the numerical simulation result with that of the formation of the jet penetrating concrete target formed by the traditional shape charges structure,the jet formed by the new star shaped liner has stronger destructive power on the concrete target,which lays the foundation for the structure design of the new tandem warhead shape charge.
