摘要
陶瓷作为一种轻质高硬材料,已经广泛应用于防护小口径枪弹威胁的轻型装甲中,然而陶瓷装甲抗多次打击能力还需要提高。穿甲过程中,约束条件下瓷材料产生的Dwell现象能有效提高陶瓷的强度和硬度,从而提高陶瓷装甲的抗多次打击能力。介绍了陶瓷装甲在穿甲过程中产生的Dwell现象的定义、微观机理、影响因素以及其研究热点和研究动态。提出了仍待研究的问题并指出研究方向将集中在数值模拟计算方面。
Ceramic material with high hardness and light quality is wildly used to protect the hght armored vehicles against the threat of small-bore armor-piercing projectile. However, the ability for anti-striking many times of ceramic armour needs to be stronger. During the amour-piericing process, the hardness and intensity of ceramic under confinement condition are increased effectively by the dwell phenomene, then the ability for anti-striking many times of ceramic armour is improved. In this text the definition, microcosmic mechanism, influencing factors of the dwell phe- nomena and the trends and hotpoint of research are introduced. Finally, the research direction to be focused on numerical simulation and the questions needing to be solved are pointed out.
