Weakly Imposed Symmetry and Robust Preconditioners for Biot’s Consolidation Model

We discuss the construction of robust preconditioners for finite element approximations of Biot’s consolidation model in poroelasticity. More precisely, we study finite element methods based on generalizations of the Hellinger–Reissner principle of linear elasticity, where the stress tensor is one o...
