Kurzfassung englisch:
We consider the quasi-static Biot´s consolidation model in a three-field formulation with the three unknown physical quantities of interest being the displacement of the solid matrix, the seepage velocity of the fluid and the pore pressure . As conservation of fluid mass is a leading physical principle in poromechanics, we preserve this property using an -conforming ansatz for and together with an appropriate pressure space. This results in Stokes and Darcy stability and exact, that is, pointwise mass conservation of the discrete model.
