Abstract
In an effort to improve the fuel efficiency of automobiles, car designers are investigating new materials to reduce the overall automobile weight. Magnesium alloys are good candidates to achieve that weight reduction due in part to their low density. As part of a project on the interaction between forming and crashworthiness, constitutive parameters of AZ31B sheets were determined in order to support finite element analysis of the material response throughout the forming process and in crash structures. Stressstrain data was collected at 0.003s, 100s and 1000s in both the rolling and transverse directions. The intermediate strain-rate response was collected with an instrumented falling weight impact test for a rate of 100s, while 1000s tests were performed with a tensile split Hopkinson bar. The Johnson-Cook model was successfully fit to the experimental data which showed significant strain rate dependence in both directions.

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
