Abstract: Molecular dynamics (MD) method was used to simulate the bending deformation of graphene (GNs)/Al layered beams under transverse load and longitudinal compression, and the influencing factors of the bending characteristics of the laminated beams were investigated. It can be seen from the bending results under transverse load that the bending stiffness of the layered beam decreases with the increase of the number of GNs layers due to the effect of interlayer action. The bending mechanism of GNs/Al layered beams is not simply the addition of GNs and Al component properties, which makes it difficult to apply classical continuum mechanics to high anisotropy layered materials. In uniaxial longitudinal compression, GNs makes the slender beam more prone to buckling before plastic deformation. The critical stress (σ_cr) and critical strain (ε_cr) of buckling are mainly affected by the thickness of the repeating layer in the layered beam, especially when the thickness of the repeating layer is less than 2 nm, the σ_cr and ε_cr decrease sharply. In flexural deformation after buckling, the tension-pressure asymmetry of dislocation nucleation causes atomic defects to occur only from the compressed place. As the number of GNs increases and the distance between repeated layers decreases, the flexibility of the layered beam increases.
