Abstract
The paper deals with a closed-form continuum description of coupled fluid flow-deformation behavior of porous media with distributed strong discontinuities. Based on the underlying physics of the solid and fluid phases at the microscale, the macroscopic hydro-mechanical (HM) behavior of a representative elementary volume is eventually retrieved in the fully saturated case using the mean-field theory and Mori-Tanaka Homogenization Scheme. The heterogeneity that governs the overall HM behavior is induced by evolving microcracks described by a crack density distribution tensor. Herein, only the shape and orientation of microcracks are accounted for in the upscaling process. Examples are presented to assess the robustness of the proposed mathematical formulation. Finally, the evolution of heterogeneity in poromechanical parameters as well as hydraulic properties of the system is investigated by coupling a microcrack growth formulation under general loading conditions with fluid flow. We will briefly discuss, through material point simulations, how the proposed model can capture localized deformations and corresponding fluid transmission behavior starting from an initially homogeneous state.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
