Graphene sheets (GS), which is one of low-dimensional nanocarbon materials, and the wrinkling and bending deformation induced by lattice defects can significantly affect the mechanical properties of GS. Therefore, it is essential to understand the deformation mechanism of wrinkles and bending in order to control the mechanical properties of GS. The purpose of this study is to evaluate the validity of introducing the continuum theory equation used for colloidal films to monolayer GS with lattice defects, which can derive strain energy from parameters related to curvature, in order to elucidate the deformation mechanism of GS. Comparison of the strain energy calculated by continuum theory with the potential energy calculated by the molecular dynamic simulation shows that the energy distribution is similar in the elastic range of the model. This result is expected to contribute to the elucidation of the deformation mechanism of GS and further development of new materials.
