Abstract The large scale behavior of porous media undergoing dynamic excitations is approached using the method of homogenization for periodic structures. A short review of similar and dissimilar characteristics concerning some homogenization processes is presented which enables one to focus on the homogenization for periodic structures. This process leads to the macroscopic behavior and introduces averages of microphysical quantities and effective coefficients such as the permeability, without imposing any prerequisite on the macroscopic scale. The dynamics of three systems are studied, involving a rigid matrix as well as a single-fluid saturated deformable medium and a two-fluid saturated deformable medium. For the first two, the physical meaning of the macroscopic quantities and the energetic consistency of the macroscopic behavior are checked.
