Abstract

The influence of position effect and interface effect on the process of a tungsten alloy rod-shaped penetrator vertically penetrating a ceramic/aluminum alloy composite target plate is studied through experimental research and simulation analysis. The effect of the position effect on the protective performance of the target plate is examined by changing the impact point, while the effect of the interface effect on the protective performance of the target plate is investigated by varying the number of ceramic layers. Research on positional effects shows that when the impact point is within the range of 0 to 30 mm from the ceramic boundary, the penetration depth of the back-plane changes by 9 mm. When the impact point is within the range of 30 to 50 mm from the ceramic boundary, the penetration depth of the back-plane changes by 1 mm. It can be concluded that the protective performance of the target plate in this area is no longer influenced by the position of the impact point. In other words, the area that is greater than or equal to five times the bullet diameter from the ceramic boundary is the effective protection area of the target plate. Research on the interface effect indicates that the penetration depth of the composite target plate with three different structures at the same thickness is 40.32 mm, 47.47 mm, and 50.77 mm; that is, the ceramic protective performance decreases with the increase in the number of layers at the same thickness.
