Thermo-hydro-mechanical
=====================


Formulations:
--------------

HH and HH2 modeling:


* Pure hydraulics, without thermal, without mechanics


* HH: 2 phases, 1 component per phase


* HH2: 2 phases, 2 components per phase

Two-phase flows in porous media


* SUSHI (Scheme Using Stabilization and Hybrid Interfaces), formulation in finite volumes

Flows in a crack/propagation under fluid pressure


* Joint with hydro-mechanical coupling


*Selective integration*_ JHMS

Regularization adapted to porous media


* Volume deformation gradient modeling to avoid location problems

Damage model dedicated to heterogeneous materials


* Random distribution of micro-defects (Weibull) D_ PLAN_GRAD_SIGM + ENDO_HETEROGENE


* Rock fracturing due to gas injection


Laws of behavior
--------------------

Mechanics


* Cyclic Hujeux law: Multi-mechanism law for sands and clays, earth dikes


* Laws of Lagle and Kleine, of viscous Drücker-Prager: viscoplastic laws for rocks (especially argillites); rocks from storage sites

Hydraulics


* Mualem-Van Genuchten's law: hydrodynamic law of unsaturated soils. Taking into account the disexisting/appearance of phases. Storage site rocks
