Application of FE method in predicting the properties of nanocomposites

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.
