Abstract
Based on the theory of porous media (mixture theories extended by the concept of volume fractions), a model describing the dynamical behavio ur of a saturated binary porous medium is presented including both geo metrical and material non-linearities. Transformed toward a weak formu lation, the model equations are solved by use of the finite element me thod. Applications of the model range from one-dimensional linear prob lems to two-dimensional problems including the full dynamics and non-l inearities.
