Poromechanics is the mechanics of porous fabrics and is now a good confirmed box in lots of engineering disciplines, starting from Civil Engineering, Geophysics, Petroleum Engineering to Bioengineering. even if, a rigorous method that hyperlinks the physics of the phenomena at stake in porous fabrics and the macroscopic behaviour remains to be lacking. This ebook provides such an procedure through homogenization suggestions. carefully based in numerous theories of micromechanics, those up scaling recommendations are constructed for the homogenization of shipping homes, stiffness and energy houses of porous materials.

The specified characteristic of this publication is the stability among concept and alertness, supplying the reader with a accomplished creation to cutting-edge homogenization theories and purposes to a wide range of genuine lifestyles porous fabrics: concrete, rocks, shales, bones, etc.

The actual, absolute, and non-destructive size of residual pressure fields inside metal, ceramic, and composite engineering parts has been one of many significant difficulties dealing with engineers for a few years, and so the extension of X-ray ways to using neutrons represents an important increase.

Sample text

Roughly speaking, the microscopic description can be treated, in some sense, as the exact one whereas the macroscopic - as some approximation, useful for engineering calculations. Both descriptions are, however, formulated within a concept of the classical physics, so both are of a macroscopic nature. This note presents some results concerning mechanical and transport properties of saturated porous media. The attention is paid for phenomenon of local mass exchange due to a sorption process as well as its effect on transport and mechanical properties of porous medium.

A mathematical form of the memory function is presented for a particular microstructure. The reciprocal relations between the overall material constants, involved in the description derived, end the paper. 1 Introduction Porous media belong to a class of heterogeneous materials for w^hich a mathematical description, useful for engineering calculation, is classically proposed within a context of the continuum mechanics. This means that these materials, from engineering point of view^, are treated as macroscopically homogeneous ones.
