Abstract
Some considerations are given on the modelling of wave propagations in porous media. Two models similar to the one proposed by Biot many years ago are described and the numerical implementation using a variational formulation and a finite element approach for the solid and the fluid phase are discussed. The discretization with time may be performed with a mixed implicit-explicit scheme which can combine the advantages of each technique. Finally the case of seismic loading in the form of a given propagating free field is analyzed.
