英文摘要:
The validity of on applying the shell theory to single layer graphitic structures, such as buckball, single-walled carbon nanotube and so on is discussed by analyzing the results obtained from the first-principles calculations. It is shown that the classic shell theory based on 3-dimensional (M) isotropic materials is inapplicable to describe the elasticity of the single layer graphitic structures, while a generalized shell theory based on 2D isotropic materials holds. The reasonable concepts in the elastic theory of single layer graphitic structures are rigidity coefficients rather than the Young's modulus and Poisson ratio.
