Ice Pressure Variations during Indentation
Bibliographic record
Abstract
The Japan Ocean Industry Association made available to the IAHR Ice Crushing Working Group one data file from a field test conducted February 4, 1999. An indenter 1.5 m wide by 0.5 m high, penetrated a sea ice sheet 168 mm thick at a rate of 3 mm/s for a total penetration of 1000 mm. The entire indenter face was covered with “tactile” sensor elements, each nominally 10 mm by 10 mm. Spatial distributions of local pressure were recorded throughout the test as well as the total load measured with a load cell. Detailed analysis of the results showed that the load cell and tactile sensors gave comparable results. The tactile sensors showed a “line-like” load distribution with only about 10 % of the ice edge in loadbearing contact. “Hot-spots” of high local pressure persisted for surprisingly long periods, up to 10 s. Local pressure variations tended to be synchronous, that is largely increasing and decreasing with global load.

How this classification was reachedexpand
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.
