摘要：

The aim of this article is to study the Young's modulus and Poisson's ratio of graphene sheets using the molecular dynamics simulation. In the simulation, the graphene sheets subjected to a uniaxial tensile loading at different temperatures is performed until failure occurres. The results show that the failure strain of the graphene sheets decreases with increasing temperature. A nonlinear relation between the stress and strain is obtained. In addition, Poisson's ratio of graphene sheets increases as the temperature increases. However, Young's modulus decreased with increasing temperature.
