Elastic Parameters of Graphene in General Approach of the Valence Force Field

In order to assess the influence of non-bonded atomic interactions on the elastic properties of graphene the transition from fouratomic symmetric structural element of the lattice to tenatomic is made. This leads to the necessity take into account in the design scheme of an additional elements. The...
