Abstract
Experimental study was performed to investigate the ballistic performance of confined 90%-Al2O3 ceramic targets against long rod penetrators by the DOP(depth of penetration) test. The results indicate that the ballistic performance, in terms of differential efficiency factor and Tate target resistance, decreases with the increase of ceramic thickness and cover plates can enhance the ballistic performance. By examining the fracture and deformation in the recovered ceramic targets and cover plates, it was found that the process of penetration of long rods into ceramic targets consists mainly of initial penetration and quasi-steady penetration stages. The macro-mechanical properties of ceramics such as shear strength and compressive strength play a significant role in the initial penetration stage, and the flow properties of the pulverized ceramics govern the penetration resistance in the quasi-steady penetration stage. The initial penetration is important for thin ceramic targets while the quasi-steady penetration is a major process for thick ceramic targets.
