Jet formation and target penetration capabilities from conical shaped charges with liner geometry of five types: (1) cone, (2) round-tipped cone, (3) hemisphere, (4) ellipsoid, and (5) trumpet, have been simulated via LS-DYNA Multi-Materials Arbitrary Lagrangian Eulerian (MMALE) technique. The objective is to observe the influences of liner types on the penetration features in target block while the amount of explosive and liner material are identical in all charge cases. Simulation results show that the hemispherical liner brings out the lowest penetration, while the ellipsoid and trumpet liners are of middle performance, but, the cone and round-tipped cone liners exhibit best penetration. Shaped charges with ellipsoid liner and trumpet liner present no remarkable discrepancy on penetration depth, however, the entrance holes are dramatically different in geometrical shape. Such penetration features are anticipated to be useful in technical design of shaped charges for some specific applications.
