Polar plots of Cijklninjnknl as a function of direction n using elastic moduli predicted by the model (Cmodel, left column), and generated using elastic moduli calculated using the finite element method (Cexact, right column). The top row represents an isotropic network (ξ=0), while the bottom row represents anisotropic networks (ξ=1). The plots in the left and right columns appear identical, indicating the elastic moduli calculated using the finite element method are well matched by those calculated using the model, for both isotropic and anisotropic networks. The plot boundaries span 30MPa.
