WebJul 23, 2024 · For a network of Gaussian chains, an isotropic stretch λ = J eq (u) 1 / 3 in the principal directions leads to an elastic stress G eq (u) (1 – J eq (u)-2 / 3), as obtained by differentiating the free energy of stretching of the network (different from Ψ, the free energy of each chain) (Damljanović et al., 2005). Using Equation (4) to ... WebA general theoretical approach provides an algebraic formula for the effective elasticity of such frameworks. The method yields the effective cubic elastic constants for three-dimensional space-filling lattices with Z=4, 6, 8, 12 and 14, the last being the ‘stiffest’ lattice proposed by Gurtner & Durand (Gurtner & Durand 2014 Proc
