Modeling and Mechanics of Granular and Porous Materials

Fernandez-Merodo, L. Tongchun, and L. To improve the consistency between the mathematical symbols and their meaning, the nomenclature employed in this paper is somewhat different from that used in the related previous papers. In addition to porosity, one of the most important geometrical characteristics of a porous sample is the specific surface.
In the strict sense, there are two basic types of specific surface for a granular porous material: pore specific surface, Ssp, and porous material: pore specific surface, Ssp, and grain specific surface, Ssg.
The former is defined as the surface area of the pore walls, Sp, per unit bulk volume, Vt, namely,. If the contacts between grains were mathematical points, the two types of specific surface would have points, the two types of specific surface would have the same value. However, for a real granular medium, the contacts always have associated a given surface area, and hence these parameters are necessarily different.
