Bore-center annular shaped charges with different liner materials penetrating into steel targets

The bore-center annular shaped charge (BCASC) is a new type of shaped charge which can generate alarger-diameter hole in steel targets than classical shaped charges. In this paper, the influence of threeliner materials, i.e. molybdenum, nickel and copper, on BCASC formation and penetrating into stee...

The simulation results were wellconsistent with the experimental results. This study showed that, at 0.50Dstandoff distance, the axialvelocity of the molybdenum projectile was lower than that of the nickel and copper projectiles.
