Abstract
When swelling mudstone, its various mechanical parameters will change significantly. Establish mudstone’s fractional calculus creep damage model structure diagram, which describe the extent of damage in rock damage variable. Assumed that the stress level of rock exceeded its the long-term strength and under the condition of mudstone accelerated strain rate loading, nonlinear damage model based on fractional calculus theory was established. Therefore mudstone creep constitutive model considering the accelerated strain rate loading conditions was obtained. The results of constitutive model showed that there appears to be an exponential function between strain and time in the accelerated creep stage. The creep test data were used to verify the proposed model and the results suggested that the fractional order b was the intrinsic parameters of rock mass which could reflect its hardness. During the accelerated creep stage, fractional creep damage constitutive model could describe the stress-strain relationship well.

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
