A Morphologically Informed Formulation of Poroelasticity Under Compression
Physical properties of porous media are inherently determined by their morphological features. Distinctive behaviors of soils, rocks, and cementitious media have traditionally divided researchers into separate communities. To unify these studies in each individual porous media application, a universal poromechanics theory should account for morphological distinctions among these porous media. In this study, the morphological parameters used in composite theory are introduced to formulate a morphologically informed poroelasticity. Corresponding to the underlying morphologies for the two bounds of the bulk modulus, the formulas for the drainage and effective stress of the porous media are derived. For those porous media commonly met in engineering application, e.g. soils, the poroelasticity formulation will be developed in next stage based on the two bound formulation, i.e. by matching the coefficient in the effective stress formula with those of Terzaghi and Biot.
