Abstract

Nanoindentation has been widely used to determine the mechanical properties of pristine and polycrystalline graphene in experiments. To investigate the effects of grain size on the mechanical properties of polycrystalline graphene, we use molecular dynamics simulations to study the nanoindentation response of suspended polycrystalline graphene layer. The force-displacement behavior from the simulations enables the interpretation of Young's modulus and breaking strength of the 2D material, which are exhibited to strongly depend on the grain size.
