REVIEW ON THE PENETRATION/PERFORATION OF CERAMICS TARGETS
-
摘要: 近10年来, 有关陶瓷的材料特性和陶瓷及陶瓷复合靶的高速侵彻$\!/\!$穿甲动力学研究已成为国际冲击工程界的热点研究领域. 相关研究有着现实的军事需求和应用背景. 国内在该领域的研究工作相对较少. 本文着重给出陶瓷及陶瓷复合靶高速侵彻$\!/\!$穿甲动力学的国外研究现状.对陶瓷及陶瓷复合靶高速侵彻$\!/\!$穿甲的实验方法、作用机理和理论模型等进行综述, 介绍空腔膨胀模型在陶瓷侵彻力学中的应用以及脆性材料高速侵彻效应中的失效波效应. 文章最后给出近期可开展的工作建议.Abstract: In the last decade, the dynamic response of ceramicmaterials and the penetration/perforation of targets of ceramics,ceramic/metal, ceramic/composite and layered ceramics is an activeresearch area. It has applications, especially, in the military field. Relatively little work in thisarea is conducted in China. The present paper introduces therecent advances in this area.Theexperimental techniques, penetration/perforation mechanisms and theoreticalmodels are reviewed. The cavity expansion model in ceramics penetration andthe effect of failure wave are specially addressed. Some research proposalsare made at the end of the paper.
