Analysis of experimentally assessed EVA foams with mixed solid-shell elements capable of very large strains

We analyze, both experimentally and numerically, two EVA foam specimens with densities ρ=120kg/m3 and ρ=220kg/m3. In the numerical analysis, we use our recent finite strain element formulations based on least-squares strains (in both solid-shells and full three-dimensional discretizations). The Ogde...
