Finite Element Based Characterization of Carbon Nanotubes

摘要

In the present study 3D finite element (FE) analysis has been used to evaluate Young's modulus, shear modulus and coefficient of thermal expansion (CTE) of single-walled carbon nanotubes (SWCNTs). Both armchair and zigzag SWCNTs have been analyzed and some important observations have been made in regard to dependence of elastic moduli and CTE of SWCNTs on important parameters.
