Abstract
The impact of different temperature combination,pressure pad force and friction coefficient on FVS0812 heat resisting aluminum alloy hot drawing forming process was investigated numerically employing the finite element analysis software DEFORM3D and experimentally using the hemispheroid warm forming tests.The results show that the largest strain area appears in 1/4~1/3 of the raised mold radius in the drawing process,and the critical Damage value is 0.24 when fracture occurred.The results also demonstrate that the preferred temperature is likely to be built in workpiece deformation area by employing the cold mold,hot workpiece and the pressure edge marked with a circle,leading to the smooth strain distribution for the workpiece.Furthermore,decreasing the pressure edge force results in the reduction of fracture risk,and the good lubrication also improves the strain and the stress distributions.Excellent agreement is observed between the numerical result and the experiment for the Damage area 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
