The shear response of metallic square honeycombs
Bibliographic record
Abstract
Stainless steel square honeycombs have been manufactured by slotting together steel sheets and then brazing the assembly.Their out-of-plane shear response is measured as a function of the relative density of the honeycomb and of the direction of shearing with respect to the material axes of the square honeycomb.The response is nearly isotropic with the shear strength and reasonably insensitive to the loading direction.In contrast to the out-of-plane compressive response, the shear response is monotonically hardening and the shear strength scales linearly with relative density.A simple analytical model based upon uniform deformation of the cell walls is in good agreement with the measured shear behavior at low shear strains, and predicts the onset of wrinkling of the cell walls to reasonable accuracy.Finite element (FE) calculations are accurate up to large values of shear strain, and reveal that the shear strength of the square honeycombs is relatively insensitive to the ratio of honeycomb height to cell size.The shear strength of square honeycombs compares favorably with other competing sandwich core topologies such as pyramidal and corrugated truss cores.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
