Webgraphene), C is the 2‐D in‐plane elastic modulus, and D is the bending modulus of graphene. The derivation of Eq. (7) is similar to that for thin film wrinkling [23], except for the fact that the bending modulus of monolayer graphene is not directly related to the in‐plane modulus by the classical elastic plate theory [13]. ... WebAbstract. An analytic formula is derived for the elastic bending modulus of monolayer graphene based on an empirical potential for solid-state carbon atoms. Two physical origins are identified for the non-vanishing bending stiffness of the atomically thin graphene sheet, one due to the bond-angle effect and the other resulting from the bond ...
