Abstract :
Base on Tersoff and Lernnard-Jones potentials, molecular dynamics simulation of nanoindentation experiment on single layer rectangular graphene film is carried out. A typical force-displacement curve is obtained and the effects of various factors including indenter radius, velocities as well as boundary conditions on the simulation results are discussed. The Young´s modulus and the strength of the graphene are measured as 1 terepascals and 90 gigapascals, respectively.
