Abstract: | In this article, mechanical properties of single-walled carbon nanotubes (SWCNTs) with various radiuses under tensile, compressive
and lateral loads are considered. Stress–strain curve, elastic modulus, tensile, compressive and rotational stiffness, buckling
behaviour, and critical axial compressive load and pressure of eight different zigzag and armchair SWCNTs are investigated
to figure out the effect of radius and chirality on mechanical properties of nanotubes. Using molecular dynamic simulation
(MDS) method, it can be explained that SWCNTs have higher Young’s modulus and tensile stiffness than compressive elastic modulus
and compressive stiffness. Critical axial force of zigzag SWCNT is independent from the radius, but that of armchair type
rises by increasing of radius, also these two types show different buckling modes. |
