Abstract:
The paper presents the results of quantum-mechanical calculations of the mechanical properties of chiral carbon nanotubes. We assess the conditions under which the boundary effects can be neglected in the simulation. Tensile strength, Young's modulus and shear energy for optimized nanotubes geometry were identified. The ranges of strains of nanotubes in which they have not experienced fracture were defined.
Keywords:carbon nanotubes, Young modulus, shear modulus, ultimate stress.
