Nanotube Bending Due to Central Loading
This paper investigates the behaviour of carbon nanotubes under central loading by diamond indentors. Molecular dynamics simulations were performed on short and long carbon nanotubes of various radii using spherical diamond indentors for loading. It was found that the zigzag tube fails after it reaches a bending angle of 62° and a global strain of 14.5% irrespective of the tube radii, that the maximum load the tube can endure increases with the tube radius but is independent of the tube length, and that the deformation capacity of a carbon nanotube (CNT) varies with the type of loading.
