Abstract
This paper presents finite element analysis of a rectangular membrane with elliptical boundary cuts under various loading conditions. A thermo-mechanical analysis investigates the effects of heat loads on the wrinkling and wrinkle reduction using boundary forces. A localized heat load will cause thermal expansion of the membrane close to the heat source while further areas will remain unaffected. The expansion of the heated area will cause compressive stresses where it meets unaffected regions causing wrinkles to form. To remove the wrinkling due to thermal loads, various tension force combinations are analyzed and the results show that it is possible to do so, and an appropriate tension scheme is set up. To try to validate the results from analysis, preliminary experimental data is compared to the results obtained from Abaqus.

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
