功能梯度碳纳米管增强复合材料结构建模与分析研究进展

摘要

Functionally graded carbon nanotube reinforced composite (FG-CNTRC) is a new generation of advanced composite materials, where carbon nanotubes (CNTs) are used as the reinforcements in a functionally graded pattern. The mechanical behavior of FG-CNTRC has emerged as one of the recent hot research topics in materials science and engineering. This paper presents a review of the developments in the modeling and analysis of FG-CNTRC structures. The emphasis are put on the linear and nonlinear bending, buckling and postbuckling, and free and forced vibration of FG-CNTRC beams, plates, shells and shell panels under various loading, boundary and environmental conditions. The presented progresses lay foundation for future studies in the area of FG-CNTRC structures. Some critical aspects for further explorations are highlighted.%功能梯度碳纳米管增强复合材料是一种新一代的先进复合材料。在这种材料中，碳纳米管作为增强体在空间位置上梯度排布。功能梯度碳纳米管增强复合材料的力学行为已成为近年来材料科学与工程科学的研究热点。本文对功能梯度碳纳米管增强复合材料结构的建模与分析的研究进展进行评述，集中讨论功能梯度碳纳米管增强复合材料梁、板、壳在各种载荷条件下，边界条件下和环境条件下的线性和非线性弯曲、屈曲和后屈曲、振动和动力响应。文中所列成果可以看作是进一步研究的基石。最后，提出需要进一步研究的方向。
