Mixed finite element and TPSA finite volume methods for linearized elasticity and Cosserat materials
Jan Martin Nordbotten, Wietse M. Boon, Omar Duran +1
Cosserat theory of elasticity is a generalization of classical elasticity that allows for asymmetry in the stress tensor by taking into account micropolar rotations in the medium.…
Modelling and discretization of flow in porous media with thin, full-tensor permeability inclusions
Michele Starnoni, Inga Berre, Eirik Keilegavlen +1
When modelling fluid flow in fractured reservoirs, it is common to represent the fracturesas lower-dimensional inclusions embedded in the host medium. Existing discretizationsof fl…
Numerical modelling of convection-driven cooling, deformation and fracturing of thermo-poroelastic media
Ivar Stefansson, Eirik Keilegavlen, Sæunn Halldórsdóttir +1
Convection-driven cooling in porous media influences thermo-poro-mechanical stresses, thereby causing deformation. These processes are strongly influenced by the presence of fractu…
Numerical modeling of wing crack propagation accounting for fracture contact mechanics
Hau Dang-Trung, Eirik Keilegavlen, Inga Berre
As a consequence of shearing, wing cracks can emerge from pre-existing fractures. The process involves the interaction of sliding of the existing fracture surfaces and the tensile…
Verification benchmarks for single-phase flow in three-dimensional fractured porous media
Inga Berre, Wietse M. Boon, Bernd Flemisch +23
Flow in fractured porous media occurs in the earth's subsurface, in biological tissues, and in man-made materials. Fractures have a dominating influence on flow processes, and the…
Finite volume discretisation of fracture deformation in thermo-poroelastic media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
This paper presents a model where thermo-hydro-mechanical processes are coupled to a deformation model for preexisting fractures. The model is formulated within a discrete-fracture…
