Abstract

In this study, microstructure-dependent static bending analysis of carbon nanotube-reinforced composite (CNTRC) strain gradient microbeams is performed. Four different patterns of CNTs are considered as uniform distribution (UD-Beam), X-Beam, Λ-Beam, and O-Beam. The equilibrium equations are achieved by implementing a variational principle based on Lam’s strain gradient theory and several beam theories. Navier’s solution procedure is utilized to solve the resulting equation for simply supported boundary condition. The influences of small size, slenderness ratio, loading types, volume fraction and the pattern of reinforcement on the deflections are perused in detail.

cnt增强复合材料应变梯度微梁的弯曲分析

在这项研究中，碳纳米管增强复合材料（CNTRC）应变梯度微梁进行了微观结构相关的静态弯曲分析。四种不同的碳纳米管模式被认为是均匀分布（UD-Beam）、X-Beam、Λ-Beam和O-Beam。平衡方程是基于Lam应变梯度理论和几种梁理论的变分原理得到的。采用纳维叶解法求解简支边界条件下的结果方程。详细研究了小尺寸、长细比、加载类型、体积分数和配筋方式对挠度的影响。

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
