Abstract

fetched live from OpenAlex

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,.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
