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 be properly solved. In this study two advanced constitutive models for sand and clay are introduced. Detailed numerical implementation of the models and the verification and validation issues related to fully coupled modeling and simulations of porous media are presented and discussed. The verified and validated methods and models are used for numerical study of layered soil deposits, with...
