摘要

对功能分级石墨烯-微晶板增强复合材料（FG-GPLRC）环形板的振动问题进行了数值分析。由于板材不同层的增强小板数量不同，因此板材具有分层结构。根据中厚板的 Mindlin 理论，采用微分正交法 (DQM) 研究了它们的基频。前五个自然频率的计算结果表明，该方法得出的结果与科学文献中报告的数据相当吻合。在研究复合环形板的自然频率时，考虑了其不同的几何参数：外部尺寸比、GPL 重量分数、GPL 分布模式和 GPL 尺寸比。

Vibration Analysis of Shearable Composite Annular Plates Reinforced by Graphene Nanoplatelets Using the Differential Quadrature Method

A numerical analysis of the vibration problem for the annular plates from functionally graded graphene-platelets-reinforced composites (FG-GPLRC) was carried out. Since the amount of reinforcing platelets was different in different layers of the plates, they had a stratified structure. Based on Mindlin’s theory of moderately thick plates, the differential quadrature method (DQM) was used to study their fundamental frequencies. The first five calculated natural frequencies showed that this method gives results rather well agreeing with data reported in the scientific literature. The natural frequencies of the composite annular plates were studied considering their different geometric parameters: ratios of their external dimensions, GPL weight fractions, GPL distribution patterns, and GPL dimension ratios.
