Abstract
Failure of a single-atomic-layer graphene sheet is analyzed in plane tension under the varying biaxiality condition. The analysis is based on the combined use of continuum and molecular mechanics where the strain energy is expressed with the help of the Tersoff-Brenner atomistic potential. A critical failure surface is produced for strains in biaxial tension. It is found that the anisotropy of graphene has a pronounced effect on its strength.
