Beschreibung:
The note is devoted to the analysis of contributions of relative accelerations to partial momentum balance equations of multicomponent models of porous materials. We show that such contributions violate the principle of material ob jectivity. Even if we ignore this principle contributions of relative accelerations are either undistinguishable from other contributions or yield unacceptable modes of propagation of sound waves or both. Consequently we conclude that such contributions should be ignored completely in the construction of macroscopical models of porous materials.
