%X Modeling and simulation allow methodical variation of material properties beyond the capacity of
experimental methods. Due to the hexagonal structure of graphene, it is considered as frame-like
structure. In the frame, covalent C-C bonds are taken as beams joined together with carbon atoms
placed at the joints. Uniaxial beam elements, defined by their cross-sectional area, material properties,
and moment of inertia represent the covalent bonds. The parameters of the beam elements
are determined by establishing equivalence between structural and computational mechanics.
However, the bonds connecting the carbon atoms do not have physical existence as they are a
compromise between attractive and repulsive forces. Also, defects at nanoscale make graphene
different from frame-like structure. In addition, the topography of graphene makes it non-linear
structure and even the axial loading changes to eccentric loading. Here we show that, by using basic
statics principles, disparities between graphene and frame-likes structures can be highlighted.
