3.3.1.3 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 is the spatial tangent of the effective hydraulic permeability with respect to the effective concentration.
The next term reduces to The following term is where and is the spatial tangent of the diffusivity with respect to the effective concentration.
The last term is where we similarly used a backward difference scheme to discretize the time derivative.
