Normal-normal continuous symmetric stress approximation in three-dimensional linear elasticity
Carsten Carstensen, Norbert Heuer
We present a conforming setting for a mixed formulation of linear elasticity with symmetric stress that has normal-normal continuous components across faces of tetrahedral meshes.…
