对具有弹性约束边和内支承的碳纳米管增强功能梯度复合材料板进行了几何非线性分析。所考虑的板是薄至中等厚度，承受大挠度，因此，一阶剪切变形理论（FSDT）和冯卡门假设被采用。通过IMLS-Ritz方法导出了该问题的控制方程。CNT增强复合板被认为是：（i）均匀分布的;和（ii）功能梯度分布的CNT增强，其中CNT增强复合板的材料性能在厚度方向上的功能梯度。研究了几个具有不同类型内支撑和弹性边约束的算例。各向同性的情况下的结果可能的验证文献中报道的已发表的解决方案的目的。
This paper presents a geometrically nonlinear analysis of carbon nanotube (CNT) reinforced functionally graded composite plates with elastically restrained edges and internal supports. The plate considered is of thin-to-moderate thickness undergoing large deflection; hence, the first-order shear deformation theory (FSDT) and von Kármán assumption are adopted. The governing equation to this problem is derived through the IMLS-Ritz method. The CNT-reinforced composite plates considered are: (i) uniformly distributed; and (ii) functionally graded distributions of CNT reinforcement, in which the material properties of CNT-reinforced composite plates are functionally graded in the thickness direction. Several example problems with different types of internal supports and elastic edge restraints are studied. Results for isotropic cases are presented for the purpose of possible verification of the published solutions reported in the literature.
