A unified failure envelope for isotropic fresh water ice and iceberg ice
Bibliographic record
Abstract
A unified 3-D failure criterion for both isotropic fresh water ice and iceberg ice is presented. The need for such a general 3-D failure formulation stems from the fact that, during collisions of small icebergs with marine vehicles, ice at the ice-ship interface undergoes a complex state of deformation and stress before it fails and breaks away, and the use of the uniaxial strength of ice to compute impact loads may lead to inaccurate ice loads calculations. The present failure criterion is developed on the basis of three different sources of experimental data. A total of about 300 trixial tests were used, which covered a wide range of strain rates (10 to the -6 s to the -1 to 10 to the -1 s to the -1), a wide range of confining stress (0.1 to 85 Mpa), and a wide range of temperature (-1° to -45° C). The analysis of the results of all these tests demonstrate the existence of a unified failure envelope for both isotropic fresh water ice and iceberg ice.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
