Abstract

fetched live from OpenAlex

Dans les alliages Al-Mg, les instabilites mecaniques, connues sous le nom de phenomenes de Portevin-Le Châtelier (ou effet PLC), se traduisent par des effets de localisation de la deformation plastique sous certaines conditions de vitesse de deformation et de temperature. Lors d’essais de traction, les instabilites PLC sont mises en evidence par des irregularites typiques sur la courbe force vs deplacement. Dans la presente etude, on se propose d’evaluer l’influence de la longueur de l’eprouvette sur les parametres de l’instabilite PLC. A cet effet, des essais de traction a temperature ambiante ont ete menes sur des eprouvettes de differentes longueurs decoupees selon la direction du laminage. L’evolution, a l’echelle locale, des composantes du champ de deformation est obtenue en utilisant une technique d’analyse par correlation d’images.

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.
