Porous media at finite strains. The new model with the balance equation for porosity (English)
0 references
The purpose is the presentation of the governing equations describing the two-component porous material as the mixture with the additional field of the porosity. The additional field equation for this field is proposed. The governing equations are formulated in the Lagrangian description. The constitutive relations under arbitrary elastic deformations of the skeleton are proposed. Various simplified models and their basic properties such as the propagation of sound waves are discussed.
