Yet another best approximation isotropic elasticity tensor in plane strain

Jendrik Voss, Panos Gourgiotis, Peter Lewintan +2

For plane strain linear elasticity, given any anisotropic elasticity tensor ${\mathbb{C}}_{\mathrm{aniso}}$, we determine a best approximating isotropic counterpart ${\mathbb{C}}_{\mathrm{iso}}$…
