heal.abstract	Fully coupled, porous solid-fluid formulation and related modeling and simulation issues are presented in this work. In particular, coupled dynamic field equations with u - p - U formulation are used to simulate pore fluid and soil skeleton responses. Present formulation allows, among other features, for water accelerations to be taken into account. This proves useful in modeling dynamic interaction of media of different stiffness (as in soil-foundation- structure interaction). Fluid compressibility is also explicitly taken into account, thus allowing excursions into modeling of limited cases of non-saturated porous media. One of the main challenges in modeling saturated soils is the appropriate modeling of elastic-plastic behavior of soil skeleton. This challenge is met with the use of an advanced material model and is discussed at some length. Illustrative examples describing dynamical behavior of porous media (saturated soils) are presented. Of particular interest is the verification and validation (V&V) of current models and simulations, and examples will be used for that purpose. Copyright ASCE 2007.	en
