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 fr a mework 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.
