The buckling behavior of carbon nanotubes(CNTs) under compression is simulated, by using the Tersoff-Brenner potential to describe the interactions in CNTs. The results show that Young modulus of CNTs decreases as the radii of CNTs increase. The Young modulus of zigzag CNT is higher than that of armchair CNT. The micro characteristic of the nanotube buckling is explained from the viewpoints of energy and structure distortion.
