Abstract

The ballistic performances of laminated ceramics were investigated experimentally and numerically and then compared with monolithic ceramics. Sixteen ceramic configurations were generated using two geometry types (hexagonal and square) and combination of three ceramic materials (Al₂O_3, SiC, and B₄C). Depth of Penetration ballistic tests were employed to evaluate their ballistic performance. According to the results, monolithic ceramic has higher ballistic performance than all laminated ceramic combinations. In laminated ceramics, using thicker ceramic on the strike-face increases the ballistic efficiency more than using it on the backing face. In addition, when a backing-face ceramic is combined with a more efficient strike-face ceramic, the ballistic performance is better than combination of same ceramic material. Lastly, finite element analysis were performed to simulate some of the tested configurations having SiC ceramic type. A similar trend was observed between the simulations and the tests.

层状陶瓷弹道性能的实验和数值研究

实验和数值研究了层状陶瓷的弹道性能，并将其与整体陶瓷进行了比较。利用两种几何类型（六边形和方形）和三种陶瓷材料（Al2O3、SiC 和 B4C）的组合生成了十六种陶瓷构型。采用穿透深度弹道测试来评估它们的弹道性能。结果表明，整体陶瓷的弹道性能高于所有层状陶瓷组合。在层压陶瓷中，在打击面使用较厚的陶瓷比在背衬面使用较厚的陶瓷更能提高弹道效率。此外，当底面陶瓷与效率更高的打击面陶瓷组合在一起时，其弹道性能要优于相同陶瓷材料的组合。最后，我们还进行了有限元分析，模拟了一些使用碳化硅陶瓷的测试配置。模拟结果与测试结果呈类似趋势。

期刊介绍： The International Journal of Impact Engineering, established in 1983 publishes original research findings related to the response of structures, components and materials subjected to impact, blast and high-rate loading. Areas relevant to the journal encompass the following general topics and those associated with them: -Behaviour and failure of structures and materials under impact and blast loading -Systems for protection and absorption of impact and blast loading -Terminal ballistics -Dynamic behaviour and failure of materials including plasticity and fracture -Stress waves -Structural crashworthiness -High-rate mechanical and forming processes -Impact, blast and high-rate loading/measurement techniques and their applications
