Interaction between level ice and conical structures: centrifuge simulations. Phase II
Bibliographic record
Abstract
This paper is a follow-up of a previous study on the interaction between upward-breaking conical structures and level ice in a centrifuge. New data were collected from a series of ten ice sheets grown at an inertial acceleration equivalent to 30 times Earth's gravity (30g). A small conical structure was driven against this ice, which ranged in thickness from 5 to 20 mm. Interaction velocities between the structure and the ice were 7,10,40 and 100 mm/s and inertial accelerations were 1 (noram gravity), 30, 60, 80 and 120g. Cones with slopes of 45, 60 and 75 deg. with respect to the horizontal were used. A description of ice rubble build-up against the cone is presented. The horizontal and vertical loads are compared with a prediction algorithm taking into account the 3D nature of the ice loads. The influence of displacement rates is also discussed.

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.
