The transverse elasticity of bilayer graphene

We demonstrate that the mechanical behaviour of bilayer graphene can be predicted using a first order deformation approach typical of sandwich structures. The mechanical transverse deformation of bilayer graphene under central loading is simulated using a mixed atomistic continuum – Finite Element technique, and the results post-processed using a First Order Sandwich Structures (FOSS) deformation approach. The proposed technique provides good agreement with experimental and theoretical data available in open literature.
