Abstract
In order to study the damage effect of blast-killing warhead on steel target at different falling velocities and falling angles, AUTODYN-3D software was used to numerically simulate the damage of blast-killing warhead on steel target at different falling velocitis and falling angles using SPH algorithm. The results show that the hole shape of the target plate is quadrilateral when the falling angle is 0°, the hole shape of the target plate is round when the falling angle is 90°, the hole shape of the target plate is circular and fan-shaped when the falling angle is 30° and 60°. At the same falling angle, the hole area of the target plate increases with the increase of falling velocities. At the same falling velocities, the hole area of the target plate increases first and then decreases with the increase of falling angle.
