Abstract

The dependence of the mechanical properties such as modulus and the strength on their diameter of fourterminal SWCNT junctions is studied using molecular dynamics simulations under tensile loading. The (4, 4), (6, 6) and (8, 8) junctions are considered. The simulation results show that the modulus and the strength decrease with the increase in diameter of the SWCNT. Two types of deformation mechanisms under loading are observed.
