Nano-indentation of circular graphene flakes are studied by using Molecular Dynamics simulation.
We show that the theory of continuum elasticity based on
nonlinear Föpple-Hencky equations
is applicable on a circular suspended graphene flake. Our simulation results are plenty compatible to those results calculated by the nonlinear elasticity theory. We find the force-displacement curves in good
agreement with the recent experimental measurements and conclude they are temperature independent.
We find as well the vibration frequency for such a system and monitor that it behaviors as a sinusoidal manner at small circular graphene size.
