| Abstract | The complete energy expression of a deformed single-walled carbon nanotube ~SWNT! is derived in the continuum limit from the local density approximation model proposed by Lenosky et al. @Nature ~London! 355, 333 ~1992!# and is shown to be consistent with the classic shell theory by which Young’s modulus, the Poisson ratio, and the effective wall thickness of SWNT’s are obtained as Y54.70 TPa,n50.34, andh 50.75 Å, respectively. The elasticity of a multiwalled carbon nanotube ~MWNT! is investigated as the combination of the above SWNT’s of layer distance d53.4 Å and the effective Young’s modulus of the MWNT is found to be an apparent function of the number of layers, N, varying from 4.70 to 1.04 TPa for N51 to `. |
