Conservation of Mass for the Solids

On a geological time scale the conservation of mass for the solid phase is determined by the deformation of the solid matrix and the accompanying time-changes of porosity, and the dislocation of the solid matrix in space. The deformation and dislocation of the solid matrix depend on the changing stress, groundwater pressure, temperature and chemical conditions. 

The general expression for the conservation of mass for the solid phase in a deforming medium may be given as (Palciauskas and Domenico, 1989)... 

From conservation of mass for the solid component,/iVy.is constant, equal to A N/ps, where is the areal mass, p, is the fibre density and N is the number of layers. Thus, with [Pg.359]
