Abstract
An analytical molecular structural mechanics model for the prediction of mechanical properties of defect free and defected carbon nanotubes is developed by using finite element method. The finite element models are developed using FE software Ansys. The developed models are capable of predicting Young’s moduli, Poisson’s ratio of carbon nanotubes under cantilever loading conditions. The response of finite element models showed that the mechanical properties of single walled carbon nanotubes Young’s moduli are sensitive to the tube thickness. Young’s modulus and Poisson’s ratio of armchair (3, 3) carbon nanotube with defect free, vacancy defect and stone wales defect is determined and the results are verified with existed literature for defect free condition.
