▎ 摘  要

NOVELTY - The method involves generating a single-layer graphene sheet periodic structure in Lammps software. A Dreiding force field is applied to generate different graphene sheet folding structures at different molecular dynamics temperature. A two-dimensional triangular grid is divided according to a position of a carbon atom in the graphene sheet layer. The graphene sheet is embedded into a three-dimensional ellipsoid. A mechanical property of the ellipsoid is calculated by using a self-model to calculate a macroscopic material. USE - Method for predicting mechanical property of resin-based composite material reinforced by graphene. ADVANTAGE - The method: combines the molecular dynamics and finite element method and self-adaptive analysis method, using multi-scale numerical simulation method, to predict and analyze the mechanical property of the graphene composite material, which can effectively improve mechanical property precision of the composite material graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a graphene wrinkle structure of the method for predicting mechanical property of resin-based composite material reinforced by graphene.
