چکیده مقاله:

Graphene is a state-of-art material, known by its unique mechanical, thermal, optical and electrical properties. Presently, the excellent mechanical behaviour of graphene has leading it to be employed in composite materials with notable capability of improvement. Since its discovery in ۲۰۰۴ (Nobel prize in ۲۰۱۰), graphene -a single sheet of carbon atoms forming the thinnest free standing material to date- has attracted enormous interest due to its potentially tunable and exotic structural and electronic properties. In this paper, First, the mechanical properties of pristine graphene are extracted through a refined finite element model that simulates its nanostructure, and where covalent bonds are regarded as structural elements. Then, the atomistic representation of graphene is assembled into a suitable representative element under different loads. Ultimately, by comparing stipulated method to other famous methods in literature, it is shown that by using this method we can predict elastic properties of any nanomaterial
