Graphene is a new type of low-dimensional carbon material, which emerged after the discovery of fullerenes and carbon nanotubes. Due to its single atomic layer thickness, graphene is considered to be a two-dimensional material, which consists of carbon atoms in a honeycomb lattice structure. Since its news-breaking appearance in 2004 [1], graphene has received significant attention due to its outstanding physical properties such as high thermal conductivity [2], stiffness, and strength [3]. However, the issue of mechanical properties of single-layered graphene sheets (SLGS) being impaired by atom vacancy defects has received scarce attention yet. However, due to limitations in the graphene production, imperfections, such as adatoms, Stone-Wales defects, line defects, and vacancies of atoms cannot be avoided in graphene nanostructures [4]. Of these, the vacancy defects are the most typical for graphene and strongly affect the mechanical properties of SLGS. Therefore, it is of high theoretical significance and practical importance to study the influence of double-atom vacancy defects (DAVD) on the mechanical properties of SLGS. Numerous researchers have investigated the elastic properties of graphene using various theoretical methods. Thus, Pei et al. applied the molecular dynamics approach to estimate the elastic modulus values for different chirality graphenes, including the so-called
