Abstract: Based on the idea of layered method, the finite element analysis of graphene-reinforced functionally graded beam is carried out in this paper. In the layered model of finite element calculation, the material parameters of each layer are constant, and the values of those material parameters are calculated according to the modified Halpin Tsai model. Then, the finite element modeling and mechanical analysis of the graphene-reinforced functionally graded beam are completed according to the standardized steps of finite element method. Numerical examples are presented to analyze the influence of the mass content, distribution patterns and size of graphene on the bending properties of the beam. Numerical results show that adding a small amount of graphene can significantly reduce the bending deflection of the beam, and distributing more graphene on the upper and lower surfaces of the beam is the most effective method to reduce the bending deflection. At the same mass content, the square graphene sheet with larger length thickness ratio can improve the bending performance of the beam more.
