Abstract
Abstract Abstract A combined experimental, analytical and numerical/FEM study on the quasi-static axial crushing of thin-walled aluminum S-rails is presented. Quasi-static test was performed on S-rails with a prescribed cross-head speed 10 mm/sec. Finite element models were developed and found to reproduce the crushing response to a significant degree of accuracy with respect to the onset of collapse, the subsequent localization of plastic deformation and the overall energy absorbing capability. With the failure parameters calibrated from uniaxial tensile tests, FEM simulation can also be used to predict the fracture onset. Based on a simplified model, an analytical solution for the force-deflection response was developed, which can be applied to an early design stage of the ȁSȁ frame. Finally, the same problem was solved by means of CrashStudio and comparisons were made with some known solutions.

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
