The formation of a fracture network in rocks has a crucial control on the flow behaviour of fluids. In addition, an existing network of fractures , influences the propagation of new fractures during e.g. hydraulic fracturing or during a seismic event. Understanding of the type an ...
The transition from elastic to inelastic deformation occurs at the yield point in a stress-strain diagram. This yield point expresses the moment when a material undergoes permanent deformation and is marked by the onset of fracturing in the brittle field at relatively low pressur ...
