Abstract
Experimental investigation of high velocity perforation of 2/1 and 3/2 GLARE 3 target panels with flat ended projectile was presented. Also, numerical simulations were carried out using explicit nonlinear finite element software, LS-DYNA, considering strain rate hardening effects. The ballistic limit was determined experimentally and numerically. Some GLARE 3/2 laminates with different Aluminium thickness is considered. The Aluminium thickness varies in frontal, medial and distal layers of GLARE, while the thickness of glass/epoxy layers is constant, and the ballistic limit and absorbed energy of each GLARE target is determined numerically. Specific absorbed energy is defined as goal function and should be maximized. The laminate with maximum specific absorbed energy is determined. In addition, energy absorbing portion of each layer is determined. There is a reasonable agreement between numerical and experimental results.

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
