Abstract

Nanocomposites have low weight and the improvement in properties is significant due to their nanostructure. Finding the properties of nanocomposites by experimental or computational methods is the priorities of researchers. Numerous studies on stress-strain behavior, strength, elastic-plastic behavior, bending, buckling, torsion, and other material behavior have been performed using the finite element method, which was reviewed in this study. In all the researches, the results obtained from the finite element method were in proper agreement with the experimental and analytical results. The use of the finite element method allows further studies on nanocomposites, which may not be possible in an experimental method or may require a lot of time and cost. In the following, a model of copper/CNT nanocomposite was studied using finite element method. The model was composed of a CNT in a box of pure copper. The stress contour and displacement contour of model was obtained and the results showed a 135% growth in nanocomposite Young’s module.

有限元法在预测纳米复合材料性能中的应用

纳米复合材料具有重量轻、性能显著提高的特点。通过实验或计算方法发现纳米复合材料的性能是研究人员的重点。许多关于应力-应变行为、强度、弹塑性行为、弯曲、屈曲、扭转和其他材料行为的研究已经使用有限元方法进行了，在本研究中进行了回顾。在所有的研究中，有限元法得到的结果与实验和分析结果吻合较好。有限元方法的使用允许对纳米复合材料进行进一步的研究，这在实验方法中可能是不可能的，或者可能需要大量的时间和成本。本文采用有限元方法对铜/碳纳米管纳米复合材料模型进行了研究。该模型是由一个碳纳米管在一个纯铜的盒子。得到了模型的应力轮廓和位移轮廓，结果表明纳米复合杨氏模块的应力和位移增长了135%。
