Abstract

fetched live from OpenAlex

This paper is a summary of recent research and development in areas related to the ultimate strength of ageing ship hulls, undertaken by the authors. Some relevant methodologies for modelling the two age-related structural degradation factors, namely corrosion and fatigue cracking damages, are proposed and studied. The effects of corrosion and fatigue cracking damages on the ultimate strength of ship panels are investigated by non-linear finite element analyses and mechanical tests. The variations of ship hull ultimate strength as a function of age-related structural degradation are investigated by progressive collapse analyses using the idealized structural unit method (ISUM). Important insights and findings obtained by the research are noted and recommendations are made regarding future development work where appropriate. The development of procedures and criteria for the damage-tolerant design of ship structures is an eventual goal, and the overall outlook in this regard is promising.

Full frame distilled prediction

Teacher imitation

Not 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.
