摘要：

During last few years there has been growing interest of researchers to the effect of elastic strain on mechanical and physical properties of graphene. In this work, by means of molecular dynamics simulations, neglecting the effects of thermal fluctuations and boundary conditions, the stability region of flat graphene was found in the three-dimensional space of plane strain components. Density of phonon states of graphene under elastic strain was calculated and the postcritical behavior was analyzed. Results obtained with the use of two different interatomic potentials were compared, and only quantitative but not qualitative differences were revealed.
