▎ 摘 要
The mechanical properties of rGO/Al composites, considering the damage and failure behaviours, are studied by finite element analysis in this paper. A numerical 3D structural model of the bulk reduced graphene oxide (rGO) nanosheets with two different lateral sizes (0.23 mu m and 1.1 mu m) is created based on AFM images. A representative volume element with 3D realistic microstructure was used to represent the selected composite microstructure. The 3D program developed can predict the elasto-plastic response and fracture behaviour of the actual rGO/Al composites. Based on the 3D structural models, the simulated stress-strain curve and the fracture morphology were verified by the experimental results. The numerical results can be used to provide insight into the deformation and fracture mechanisms of rGO/Al composites.
