Non-Linear Modeling of Single-Walled Carbon Nanotubes

Abstract

The present paper deals with the numerical evaluation of the effective Young's modulus values for the single-walled carbon nanotubes. The analysis is focused on the definition of the interatomic interactions applying the linear and non-linear numerical procedures and their influence on the results. The interatomic potentials, the continuum mechanics, and the finite element method are used in the conducted study. The non-linear numerical procedure revealed the variation of Young's modulus values for the carbon nanotubes during deformation.
