Molecular dynamics and quantum mechanics are the best method for analysis the CNTs behavior. Bur because of the difficulties and cost, this task is limited to small structure with limited atoms number. In this paper, continuum mechanics theory base on the Cauchy-born role has been used for this goal according to the experimental and theoretical results. This analysis includes both elastic and inelastic behavior despite serious challenges in inelastic field. In this paper the virtual definition of thickness in SWCNT and MWCNT are reviewed. Then the validity of this definition in different loading and elastic and inelastic region is discussed. Then a FEM model of CNT in different load combination is developed with advanced capabilities like large deformation. The result of this model is compared with some experimental and MD model's results and shows that the continuum mechanic's modeling of nanotubes could help to predict of behavior of nanostructure and nanocomposite despite serious limitation.
