Mechanical properties study for graphene sheets of various size

Authors: Kirillova I. V., Kossovich E. L., Fadeev A. A.

We studied mechanical properties of large graphene sheets. The Young's modulus was found for each of the considered nanoparticles and sheets. To this end, the deformation was applied in two orthogonal directions – zigzag and armchair directions of the graphene atomic framework. It was established that there exist a size effect on the Young's modulus of graphene.
