Numerical simulation of jet formation by wide angle shaped charge and penetration into multi-layer targets

Based on MOCL algorithm, jet formation by wide angle shaped charge and penetration into multi layer targets are numerically simulated with a two dimensional multi material Eulerian code. The computation results agree with the experimental 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 percent of the liner, and it has the characteristics both of shaped charge jet and explosively formed projectiles, which is helpful for penetrating into multi layer targets.
