The method of spatial averaging is apphed to derive a macroscopic form of Fick's law for unsteady diffusion through a rigid porous medium The validity of this form is found to be restricted by the requirements that diffusion is quasi-steady on a pore scale and that interphase mass transfer rates dep
Stress strain relationships of a granular system are derived based on the premise that the mean field of displacement is the best fit of actual particle displacements. Based on the best fit hypothesis, two fundamental relationships are derived: (1) the average strain as a function of contact displac
