摘要

碳纳米管(CNTs)在机械、电气、磁性和光学性能方面被认为是特殊的。碳纳米管复合材料在许多科学领域也发挥着至关重要的作用。本研究采用四束具有方形代表性体积单元(RVE)的CNTs，仿真使用ANSYS Multiphysics 11.0软件。本研究通过改变碳纳米管束的距离来观察碳纳米管基铝复合材料的应力分布。通过改变不同的参数来研究应力分布和横向杨氏模量。从这项研究可以知道碳纳米管束如何形成在一起，以增加或减少应力。结果表明，碳纳米管中心与参考点的距离越大，应力越小。

Stress distribution in CNT-Aluminum matrix composite by changing distances between CNT bundles

Carbon Nanotubes (CNTs) are identified as exceptional in terms of mechanical, electrical, magnetic and optical properties. CNT based composites are also playing a vital role in several fields of science. In this research, four bundles of CNTs with square Representative Volume Element (RVE) is used and ANSYS Multiphysics 11.0 software is used for simulation purpose. In this study, stress distribution of CNT based Aluminum composite is noticed by changing distances of CNT bundles. Stress distribution and transverse Young’s Modulus are investigated by changing different parameters. From this study it can be known how CNT bundles can be formed together to increase or decrease stress. The brief result is that, if the distance of CNT center from reference point is increased then the stress is decreased.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
