| Abstract: | The warhead was launched at impact velocity of 2.0Ma and 2.SMa. It impacted a 4-layer space armor steel at 0°. The process of the penetration was simulated with explicit finite element software ANSYS/LS- DYNA. The conclusion and its analysis indicated that TC4 performed well in penetrating and it could be made into the shell of missile warhead, and the warhead shell structure strength was strong enough to satisfy the need of penetration. |
