In a given paper, the analysis of size-dependent mechanical properties of the armchair single-walled carbon nanotubes is presented. This investigation is based on molecular mechanics method, classical mechanics, and elasticity theory. The mathematical model of an explored nanotube is elaborated and implemented in a computer program. The results of numerical experiment reveal the dependence of Young's modulus and shear modulus on the tube diameter: the more the diameter the stronger the dependence. No relation is revealed between the diameter and Poisson's ratio. The obtained results fit for current theoretical and experimental data quite well.
