1) When tungsten alloy fragments penetrate Q235 steel targets, it is easiest and more effective to increase the armor-piercing ability of fragments by changing the shape of the fragments. When the fragment mass and the impact speed are the same, the armor-piercing depth of cylindrical fragments with an aspect ratio of 2:1 is 1.3 to 1.5 times that of cubic fragments on average, and the difference is more obvious under high speed conditions. If the appropriate impact angle of the cylindrical fragment cannot be guaranteed, the armor-piercing ability of the fragment will be greatly reduced, so it is still recommended to use spherical fragments with stable armor-piercing ability.
2) Compared with the fragment mass and the impact speed, increasing the fragment impact speed in the same proportion can more effectively increase the armor-piercing depth of the fragment.
