    Abstract
  • A theory model to calculate the target resistance is established to evaluate the ballistic properties; the parameters used in the numerical simulations were determined by simulating the experiment of long rod penetration into alumina ceramic target; the theoretical model is proved to be reasonable by simulating the penetration of shaped charge jet into alumina ceramic. The impact of the geometric size of the shaped charge on the jet velocity and penetration results was studied. It can be concluded that the bigger the angle and the thickness of the shaped charge are, the lower the jet velocity is, and the impact of the thickness on the velocity gradient is severe; the angle of the shaped charge has a significant influence on the penetration depth.
