We simulated (LAMMPS program) the tensional behavior of CNTs with different chiral indexes (10, 10; 0, 10, and 10,0) using the original CH.airebo potentials (Stuart et al., 2000). The plot indicates the maximum tensile stress of about 60 GPa. The 0, 10 and 10, 0 CNT structures can withstand tensile stress longer (> 20 ns) than the CNT molecule (< 20 ns) with the same chiral indexes (n, m = 10).

Respected Sir, I also got difference in tensile strength with different chiralities of SWCNTs.
The chirality of the nanotube does have effect on the tensile behavior of nanotube. However, (k,0) and (0,k) nanotubes are topologically same and will behave same under tensile test.
