Intrinsic permeability by rheological dynamic
Porosity and permeability are related properties of solids that are investigated by different continuum models. Porosity has already been explained by the author as the variation of the strain energy density of a dry solid using the rheological-dynamical analogy (RDA). Permeability is traditionally, theoretically and experimentally, investigated by Darcy's law and as such depends on the properties of the fluid, water or gas flowing through the solid. This means that we do not have a defined permeability of solid matter, which is independent of the properties of water or gas. In this paper, intrinsic permeability is defined based on the rheological dynamics theory (RDT) in the state of critical damping. Furthermore, RDT defines the liquid flow criterion by the porosity threshold of the solid. Permeability defined in this way is confirmed by experimental data from the literature on the example of engineered permeable concrete.
