Abstract
In this study, the two- and three-hierarchical hybrid reentrant honeycombs were designed with reentrant hexagon as main unit, ellipse and missing-rib as support units. The effects of support units and concave Angle on compressive characteristics were explored. Through the experiment and simulation analysis, the compressive curves of the two-hierarchical honeycombs had a long plateau stage (close to 0.3 strain) in the early deformation to fully buffer. The ellipse and missing-rib made the deformation more stable, and their energy absorption was nearly twice and 1.8 times that of 2RH, respectively. The concave Angles θ and α of one- and two-hierarchies affected the later segmentation of the compressive curves. The three-hierarchical honeycombs showed that the upper layer deformed first and the lower layer deformed later. According to the Poisson’s rate-strain curves, the deformation of the lower layer of the three-hierarchical honeycombs was more severe than that of the upper layer when α = 70°, while the deformation was opposite when α = 60° and 50°. This study offered valuable insights into multi-hierarchical hybrid structures with auxetic behavior.

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
