A modified spring finite element model for graphene elastic properties study

Atomistically informed hierarchical modeling for revisiting the constituent structures from heredity and nano–micro mechanics of sheath-core carbon fiber

“…10 and was equally divided in two transverse directions. C3D8R elements were employed and initially assigned with experimental engineering constants of graphene, E axial = 1060 GPa, E out-of-plane = 36.5 GPa, G out-of-plane = 4 GPa, 67 and G in-plane = 280 GPa 68 and a Poisson's ratio value of 0.2. Imposing 1% tensile and 1.27% engineering shear strains to the RVE model, as depicted in Fig.…”
