Abstract :
[en] The paper briefly presents the main features of a hydro-mechanical coupled finite element of interface. The mechanical problems takes into account the the detection of contact, the development of a contact pressure, the shearing and the relative sliding between two solids. A three-node discretisation of hydraulic problem allows the representation of fluid flows across and in the plane of the interface. The method involves a drop of pressure between each side of the interface and the inner medium. The hydro-mechanical couplings come from 1) the definition of the total pressure acting on each side of the interface according to the Terzaghi’s principle; 2) the dependence of the permeability on the gap variation; 3) the variation of the fluid mass stored within the gap.
