碳纳米管具有优异的机械、力学、电学、化学和光学性能，具有很高的强度和韧性，

可以预见，将碳纳米管作为复合材料的增强体可以表现出良好的强度、弹性和抗疲劳性。

目前，碳纳米管基础力学行为的研究已经成为国际上的热点问题之一。本文基于连续介

质力学的理论框架，完善和进一步发展了连续介质力学的基本理论和研究方法，研究了

碳纳米管屈曲、后屈曲以及冲击载荷作用下的动力屈曲等一系列相关问题。-Carbon nanotubes have excellent mechanical, mechanical, electrical, chemical and optical properties, having a high strength and toughness, and can be predicted, and the carbon nanotubes as a composite material reinforced body can exhibit a good strength, elasticity and fatigue resistance . At present, the basic mechanical behavior of carbon nanotubes have become one of the hot issues in the international arena. Based on the theoretical framework of continuum mechanics, refinement and further development of the basic theories and research methods of continuum mechanics, the study of carbon nanotubes buckling, post-buckling, and the impact of dynamic buckling under the load range of related issues.
