Introduction ... Biot’s poroelasticity. There is a new Poroelasticity multiphysics coupling between Solid Mechanics and Darcy’s Law. Poroelasticity describes the interaction between fluid motion and deformation in the porous and porous-like media. Using the poroelasticity module of COMSOL Multiphysics we performed various types of permeation tests varying the method used for positioning the sample in the test chamber (glued sample and o-ring on top) and the level of fluid pressure. The Poroelasticity interface couples Darcy's law and solid mechanics to assess deformation of porous media that results from fluid withdrawals. To understand what is the better way to guarantee the sample seal, we evaluated the local Poroelasticity is related to the geomechanics of porous and porous-like materials. In the case of poroelasticity, the coupling parameter is the product of the Biot coefficient and the Skempton coefficient, αB, whereas the thermoelastic coupling parameter is given by Eq.
