A modified coherent potential approximation: Grain-contact moduli and coordination-number effect
We modified the self-consistent coherent potential approximation (CPA) for modeling properties of granular composite materials so that it takes into consideration the grain coordination number and distinctive elastic moduli for grain-contact zones. The original CPA was reasonably accurate for low-porosity consolidated sandstones but used only inclusion (pore or grain) shape and did not take into account morphological parameters such as coordination number and contact area or contact moduli.
