A Visco-Elasto-Plastic Stress-Strain Model for Polycrystalline Materials at High Temperatures
Bibliographic record
Abstract
This paper deals with the application of a constitutive model for ice collisions onto offshore structures and ships, through the use of numerical methods. Ice, in nature, exists at very high temperature states. Therefore, its behaviour is characterized by time dependent (visco) elasto-plastic behaviour. Also, upon loading, ice cracks (damage) and ice pieces break away from the original ice mass. This cracking activity includes both micro cracking and macro cracking. The constitutive model, presented in this paper, takes into account the micro cracking activity in ice (ice damage model). However, the macro cracking activity (large fractures in the ice mass) is considered via the numerical applications (through the death of elements, failure criterion). Validation of the model is demonstrated via comparisons of measured versus predicted behaviour,.

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.
