Abstract of the paper ``Exact results in linear thermomechanics of fluid-saturated
porous media,'' with G. W. Milton
Exact results are derived relating the various bulk moduli (frame, unjacketed,
and pore) and heat capacity of inhomogeneous fluid-saturated porous media to
the pertinent thermal expansion coefficients and component moduli when only
two porous solid constituents are present. The porous solids need not be
space filling or in perfect welded contact, so these results apply to materials
containing some voids or cracks interspersed between the two constituents in
addition to the interior voids associated with their pores. The key ratio of
fluid pressure to temperature change producing uniform expansion or contraction
is shown to be independent of porosity.
