Nano-scale finite element approach was used to predict the mechanical properties of carbon nanotubes. The unit-cell isolation scheme was same as that from Eric Seather [1], and nothing was assumed to exist inside any nanotube. Arm-chair, zigzag and chiral type of nanotubes with different radii were discussed in detail. The longitudinal modulus of nanotubes Ez was found to decrease with increasing nanotube radius, but to be independent of nanotube helicity. The modulus was not over 0.5 TPa for any case. Meanwhile, Poisson’s ratio νzθ was also predicted.
