Modélisation du crash et du thermo-estampage d’une pièce en composite à matrice thermoplastique
Bibliographic record
Abstract
Ces travaux sont dédiés à la simulation du procédé de thermo-estampage d'une pièce automobile en composite à matrice thermoplastique suivie de la simulation de la tenue mécanique de la pièce fabriquée.La simulation du procédé s'appuie sur un modèle thermo-viscohyperélastique.La simulation de la tenue mécanique a nécessité d'abord le développement et l'implémentation d'une loi de comportement en crash sous forme de subroutine Abaqus de type VUMAT.Les différents travaux de simulation ont été précédés de campagnes expérimentales pour alimenter les modèles.ABSTRACT.This works consist of the simulation of thermo-stamping process on a thermoplastic composite automotive part followed by the mechanical simulation of the manufactured part.The process simulation is based on a thermo-visco-hyperelastic model.The simulation of mechanical behavior first required the development then the implementation of crash behavior law in Abaqus subroutines VUMAT.The different simulation works have been preceded by experimental tests in order to provide input data for the models.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
