摘要
冲击载荷作用下材料与结构的响应与防护是固体力学和爆炸力学研究的热点课题,在国防工程和民用防护工程中有着重要的应用背景.本文主要评述了我国武器装备与防护工程常用材料与结构在冲击载荷作用下响应与防护的国内外研究现状与发展趋势,内容涉及材料的动态力学特性、本构关系和结构的变形与破坏等方面,着重探讨了混凝土、钨合金、陶瓷等材料的动态本构特性以及混凝土坑道、舰船等结构的防护作用机理.
Response and protection of materials and structures under impact loadings are the hot topics in solid mechanics and explosion mechanics with important application background in national defense and civil protection. The present paper mainly reviews the research status and development trend of the re- sponse and protection of materials and structures under impact loadings. The content covers the dynamic characteristic, constitutive relation and the deformation and failure of some common materials and structures in weapons equipment and protection engineering, focusing on the dynamic constitutive behavior of concrete, tungsten alloy, alumina and the protection mechanism of concrete tunnel, ship, etc.
