Coupling to Darcy’s Law for Poroelasticity Modeling

You can model the flow within porous composite laminates and its interaction with the structural shells. This interaction is supported by structural shell models based on the layerwise theory. The coupling occurs on the boundary level, where the pore pressure from the Layered Darcy’s Law interface acts as a load for the Layered Shell interface, causing swelling or shrinking. Changes in volumetric strain affect the pore space, acting as a mass source or sink in Darcy’s Law.
