It has been found that the fracture toughness of epoxy resin is increasing enormously with a very little graphene.However,the mechanism of this phenomena is not easy to understand.Therefore,in order to understand this mechanism,epoxy nano composite with graphene is simulated by using Molecular Dynamic Method.Aim of this simulation to find fracture toughness contribution with respect to graphene weight ratio.The epoxy polymer is made by epoxy monomer and curling agent(D230)by using J-Octa,which is one of material analysis software.The epoxy composite is made by setting few graphene monomers in this epoxy polymer.The graphene wait ratio can be changed by changing the number of graphene monomers.The uniaxial tensile simulation is made with and without periodic boundary condition by using Lammps,which is one of the Molecular Dynamic Method platform.The stress-strain relations are obtained with various values of graphene weight ratio.The strain energy is considered as a parameter,which indicate the toughness of the epoxy composite.And the effect of the graphene to the toughness of the epoxy resin composite is studied.The inclement of the toughness is observed with small wait ratio of graphene monomer.
