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.
