On the mechanical and hydraulic response of sedimentary rocks in the presence of discontinuities

In this study, the mechanical and hydraulic properties of sedimentary rocks are examined. The first part is focused on the analysis of the onset and propagation of damage. The formulation of the problem involves the specification of an anisotropic failure criterion as well as description of inelastic deformation, which includes the time-dependent effects. The discrete propagation of macrocracks is simulated using an enhanced constitutive law …
