Here are presented two complementary approaches : one is based on the modeling of a fracture in terms of geometry and mechanical behaviour of the joint walls ; the other on the modeling of a fracture from a local compacity variable accounting for the modification process of the fracture space available to the fluid. The results of these two approaches are presented, together with hydro-mechanical tests results on granite samples %G English %L hal-03260531 %U https://imt-mines-ales.hal.science/hal-03260531 %~ INSTITUT-TELECOM %~ EM-ALES %~ INSTITUTS-TELECOM
