mixture theory
truesdell‘s metaphysical principles
19 - theory of porous media
all properties of the mixture must be mathematical consequences of the properties of the constituents
to describe the motion of a constituent, we may in imagination isolate it from the rest of the mixture, provided we allow properly for the actions of the other constituents upon it
the motion of the mixture is governed by the same equations as is a single body.

19 - theory of porous media
karl von terzaghi [1883-1963] austrian civil engineer and geologist, father of soil mechanics

19 - theory of porous media
paul fillunger [1883-1937] austrian scientist, pioneered the study of saturated ground
terzaghi vs fillunger
19 - theory of porous media
karl von terzaghi “erdbaumechanik“ [1925] paul fillunger “erdbaumechanik?” [1936]
fillunger pioneered the study of saturated ground
he discovered the difference in behaviors of the effective and general stresses in samples of ground
he is considered to be a pioneer of the theory of liquid-saturated porous solids.
fillunger's theories put him in heated conflict with karl von terzaghi, the father of soil mechanics, whom fillunger was accused of slandering. the university blamed fillunger, who then committed suicide with his wife
