Abstract

fetched live from OpenAlex

The RFPA (Rock Failure Process Analysis) code is used to carry out the numerical test using ring specimen as a medium to determine the indirect tensile strength of rock. The effect of diameter of internal hole on failure modes and determined strength of rock specimens is discussed, and the related rock failure mechanisms are clarified. The existing practical problem found in the lab test is also explained according to numerical results. Compared with the test results, both the failure modes and peak loads show in good conformity. Moreover, based on numerical result, a new test scheme is proposed using the cracking load to determine the indirect tensile strength of rock.

Full frame distilled prediction

Teacher imitation

Not 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.
