3.4.3 Linearization along
The linearization of the first term in along yields where represents the spatial tangent of the stress with respect to the effective concentration. The next term is where and are the spatial tangents of the effective hydraulic permeability and solute diffusivity with respect to the effective concentration.
The next term reduces to The following term is where The last term is where we similarly used a backward difference scheme to discretize the time derivative.
