Sažetak
The combined finite-discrete element method (FEM/DEM or FDEM) has become a tool of choice for a whole range of problems involving fracturing and fragmenting solids. The key advantage of the FDEM is the introduction of finite displacements, finite strain based deformability models combined with a suitable material law ; these are then merged with objective discrete crack initiation and crack propagation solutions that have a great deal of fidelity in reproducing complex fracture patterns and eventual fragmentation. So far, these are mostly limited to dry crack networks. Work is currently in progress at Los Alamos National Laboratory to incorporate fluid driven fracture processes into the FDEM. In this paper a novel ISF (Integrated Solid-Fluid) solver for fluid flow over crack manifolds has been developed as an integral part of this ongoing research effort.
