Abstract

fetched live from OpenAlex

In this study the effect of short and long cracks for brass alloys specimens exposed to bending cyclic load is investigated, this test applied on a group of standard specimens until its fracture, data taken could be drawn as a curve between stress and number of cycles (S-N) curves which gives the fatigue limit. Results obtained theoretically and experimentally, that are concluded decreasing in the applied load cause increasing the age and applying high loads in the beginning and at the end given almost smaller number specimen age and the quick growth of short cracks followed by quick growth of long cracks, that the values taken from the theoretical equations are always greater than experimental number of cycles of failure.   Key words: Fatigue, varying loads, short cracks, long cracks, brass alloy.

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.
