Non-linear problem of deformation of two phase porous media with induced anisotropic permeability

Marian Mikołajek

Abstrakt

The paper deals with the non-linear state of deformation of saturated two phase porous media with variable porosity and permeability. Induced anisotropic permeability is taken into account. This induced anisotropy is described by changing the internal structure of spherical pores into ellipsoidal ones. N umerical example shows the evaluation of the current tensor of permeability in the plane state of deformation.
