Numerical Simulation of the Shaped Charge Jet from Tungsten-Copper Powder Liner

Formation process of the shaped charge jet of Tungsten-Copper powder liner was simulated through numerical method with the LS-DYNA3D software.With Multi-Material ALE Algorithm,the formation process of the shaped charge jet was simulated and compared with the experimental results.The results show that the jet diameters become thinner,the head jet speed reduces with the increase of liner density,and the simulation results and experimental results are consistent.
