Mechanical Properties of Porous Solids

Discovering accurate relations between microstructure
and elastic properties of porous/microcracked solids
always was a challenging task in material science.
In the book these relations are investigated on an
example of sintered hydroxyapatite and Fontainebleau
sandstone. It is shown that isolated pores of
irregular shapes may be approximated, with good
accuracy, by the spheroidal ones. Several commonly
used approximate schemes are applied to predict
effective Young's and shear moduli of a material with
spheroidal pores. The microstructural information
(average shapes of pores) required for adequate
modeling of the isotropic elastic properties is
identified; if this information is utilized, the
usual effective media schemes provide satisfactory
predictions of the effective elastic properties. An
attempt was made to recover the information about
evolution of microstructure from the experimentally
measured elastic moduli.
The book addresses researchers, graduate and
postgraduate students, as well as engineers, in the
fields of micromechanics of solids and materials science.
