This paper aims to investigate the wave propagation analysis of multi-scale hybrid nanocomposite plates by considering the influences of the aggregation of the nanoparticles. For the constituent materials of the plate, a polymeric matrix is supposed to have macro- and nano-reinforcements dispersed in it. The well-known micromechanical methods, such as Eshelby-Mori-Tanaka model and the rule of the mixture, are exerted to compute the effective material properties of the nanocomposite plate. Also, a refined higher-order shear deformation theory is implemented to obtain the motion relations. Besides, the governing equations are derived by employing the principle of Hamilton. Then, the analytic method is used to solve the obtained governing equations of structure and finally wave frequency and phase velocity are calculated. The effects of the various parameters on the variation of phase velocity and wave frequency of the multi-scale nanocomposite plates are examined. The presented results demonstrate that the mechanical response of the system can be decreased, while the nanotubes are covered by clusters.

团聚多尺度杂化纳米复合板的波传播响应

本文旨在通过考虑纳米粒子聚集的影响来研究多尺度混合纳米复合板的波传播分析。对于板的组成材料,聚合物基质应该具有分散在其中的宏观和纳米增强材料。应用Eshelby-Mori-Tanaka模型和混合规则等著名的微机械方法来计算纳米复合板的有效材料性能。此外,实施了改进的高阶剪切变形理论以获得运动关系。此外,控制方程是利用汉密尔顿原理推导出来的。然后用解析法求解得到的结构控制方程,最后计算出波的频率和相速度。考察了各种参数对多尺度纳米复合板相速度和波频变化的影响。所呈现的结果表明,系统的机械响应可以降低,而纳米管被簇覆盖。
