Abstract:
Large-scale molecular dynamic simulations of the axial deformations in single-walled carbon nanotubes have been performed using an O(N) tight-binding method. Our simulations indicate that under large strain, 0 K stress is remarkably sensitive to helicity, and that a zigzag nanotube and an armchair nanotube are the stiffest, respectively, under elongation and compression regimes. Furthermore, the elastic properties of a graphite sheet have been investigated using a simple harmonic potential and an analytic bond-order potential. The results suggest that the unique elastic properties of carbon nanotubes originate from those of a six-membered ring.

Consider a rod that is fixed at one end and subjected to an axial force at the free end. This axial force induces stress within the rod, leading to its elongation. As the axial force increases, so does the elongation of the rod, illustrating a direct relationship between the force applied and the resulting...
