Abstract

This article presents the buckling behavior of carbon nanotubes reinforced sandwich-structured composite shells supported by elastic foundations. The sandwich-structured configuration is composed of three layers, an isotropic core, and two nanocomposite face sheets. Carbon nanotubes fibers are applied to reinforce nanocomposite face sheets of sandwich composite shells. It is assumed that the distribution of reinforcements across the shell thickness is uniform or functionally graded. Under the assumption of the thin shell, the equilibrium equation of the buckling response of CNT-RSSC shells is obtained. The pre-buckling stresses by applying Airy’s stress function and an adjacent equilibrium criterion to establish the stability equation associated with the buckling state are obtained. The effects of different types of CNTs' reinforcement, volume fractions, geometrical parameters, core to face sheet thickness ratio, and elastic foundations on the mechanical buckling analysis are examined.
碳纳米管增强三明治结构复合材料壳弹性地基屈曲分析模型
本文介绍了弹性地基支撑下碳纳米管增强夹层结构复合材料壳体的屈曲行为。三明治结构配置由三层、各向同性芯和两个纳米复合材料面板组成。碳纳米管纤维被应用于夹层复合材料壳体的纳米复合材料面板的增强。假设钢筋在壳体厚度上的分布是均匀的或功能分级的。在薄壁假设下,得到了CNT-RSSC壳体屈曲响应的平衡方程。通过应用Airy应力函数和相邻平衡准则建立与屈曲状态相关的稳定方程,获得了预屈曲应力。考察了不同类型的碳纳米管补强、体积分数、几何参数、芯板厚度比和弹性基础对力学屈曲分析的影响。
