Abstract
Abstract Linear formulations are insufficient to take into account the effect of large deflections that occur after initial buckling. This effect can only be considered in the non-linear buckling analysis. In the present work, the non-linear analysis is carried out using the finite element method based on first-order shear deformation shell theories. Two non-linear shell theories, Donnel’s and Sanders’ theories, are used in the analysis. Based on the first-ply failure analysis and non-linear buckling analysis, the critical sizes and parameters of the tapered curved plates that will not fail before global buckling are determined. A parametric study that encompasses the effects of taper angle, critical length-to-height ratio, radius, radius-to-thickness ratio and geometric parameters of the plates is conducted.

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
