Abstract: Numerical simulation of mechanical properties of silicene samples are made in the valence force field model. The dependences of elastic modules on linear dimensions are found. The results are compared with those obtained in the of central force field model. Behavior of the corresponding graphs is similar. At the same time, a lag of values of the elastic modules received within the valence force field model in comparison with the central forces field model was observed. The lag in question accrues with growth of the sample sizes.
Keywords: central force field, valence force field, silicene, Young’s modulus, Poisson’s ratio.
