摘要
将石墨烯片一致或随机地分布到基体中,形成石墨烯增强复合材料。基于考虑横向拉伸的位移场,利用哈密顿原理建立数学模型,对石墨烯增强复合材料板的弯曲行为进行分析。首先通过与已发表文献中板的自由振动频率一致性的比较,验证所建立数学模型与算法的正确性。在此基础上,对石墨烯含量、长宽比、长厚比、板的长宽比等对石墨烯的中心横向位移在厚度方向上变化的影响进行了探讨,并给出了相应的物理解释。
Multilayer graphene nanoplates was added to the matrix as reinforcements to form graphene reinforced composites. Based on the displacement field considering transverse tensile effect,a mathematical model is established by using Hamilton principle to analyze the bending behavior of graphene reinforced composites plate. Firstly,the validity of the mathematical model established in this paper is verified by comparing the frequency consistency of the free vibration with the results in published literature. Then,the effects of the aspect ratio of graphene and the length-width ratio of plate on the variation of the central transverse displacement deformation of graphene in the thickness direction are discussed,and the physical explanation of the response is given.
