| Popis: | International audience; Characterizing the path of a hydraulic fracture in a heterogeneous/jointed medium is one of the challenges of current research on hydraulic fracturing. We present here a 2D lattice hydro-mechanical model for this purpose. Natural joints are represented by introducing elements with a new plastic-damage behaviour. The action of the fluid pressure on the skeleton is represented by using Biot’s theory. The interactions of cracks on the fluid flow are represented by considering a Poisueille’s flow between two parallel plates. Numerical coupling is achieved with a staggered coupling scheme. |
