Analysis of any problem in geomechanics requires statements of equilibrium, kinematics, and the link between stress and strain change, namely the constitutive model. Highly nonlinear and anisotropic stress-strain behavior of geomaterials makes the use of realistic constitutive models imperative for successful numerical analysis of boundary value problems. The mechanical model of the solid-pore fluid interaction when combined with suitable constitutive description of the solid phase and efficient computational procedures, allows transient and static problems involving deformation to...
