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, mechanic

The ASTM standards that is used to determine the composite material properties as reuired by FAR 25 and MIL-HDBK-17F

material subroutine suitable for explicit analysis

Consider a precision structure subjected to varying thermal conditions unless carefully designed, it will distort as a result of the thermal gradients. One way to prevent this is to build the structure a thermally stable composite material this
