Modeling of Carbon Nanotubes using Finite element Analysis

E. N. Ganesh

Abstract


Carbon Nanotube (CNT) finds extensive applications and uses in various industries nowadays. Modeling the CNT using Finite Element Analysis technique is proposed in this paper. In Finite elopement analysis Embeded Region technique is utilized in this paper for Proper and accurate Modeling. The Technique combines two independent FE meshes in a single model based on the principle of equal displacements of respective nodes. Results from the ER technique have shown good correlation with those obtained from the single-mesh model. The influence of CNTs on stress fields in a UD composite was investigated. The main focus of such analysis was on the micro-scale stress concentrations. Our results indicate that agglomerates of CNTs create additional micro-scale stress concentrators. They increase stresses in the matrix that can eventually lead to the formation of microcracks.
