Numerical simulation on jet formation by wide angle shaped charge and penetration into multilayer targets

Based on MOCL (mark on cell line) method, jet formation by wide angle shaped charge and penetration into multilayer targets were numerically simulated with a two-dimensional multi-material Eulerian code. The computation results agree with the experimental results very well. The ability to coherently simulate the full process can avoid lots of artificial hypotheses in the numerical computation, and is of practical usage to the shaped charge optimization design. Numerical and experimental results show that the jet mass formed by wide angle shaped charge amounts to 32% of the liner, and it has the characteristics of both shaped charge jet and explosively formed projectiles, which is helpful to penetration into multilayer targets.
