| Abstract: |
| In this contribution we study the torsional properties for the different chiral single-walled carbon nanotube (SWCNT) based on the constitutive model established by the higher-order Cauchy-Born rule. The present investigation shows that the symmetric torsional properties existed in armchair and zigzag SWCNTs which are symmetric in structure. However, it is not the case for chiral SWCNTs which are non-symmetric in structure. Also, the shear modulus is investigated for a serial of different chiral SWCNTs in detail. The good comparison between part of the present results and that from literatures verifies the availability of the present model and the obtained results. |
