Abstract

fetched live from OpenAlex

The quasi-static and dynamic fracture behaviour of the high-strength aluminium alloy AA7075-T651 was studied by material testing over a wide range of stress states and dynamic impact testing using different shapes of the projectile. Rolled plates of the aluminium alloy exhibited anisotropy owing to the complex, non-recrystallized microstructure. In the quasi-static tests, a marked influence of loading direction on the fracture strain was observed, in addition to the expected strong effect of the stress state. Fragmentation and delamination were observed in the impact tests within the impact zone of the plates. A metallurgical study showed the crack growth to be partly intergranular, along the grain boundaries or precipitation free zones, and partly transgranular by void formation around fine and coarse intermetallic particles.

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.
