High-cycle fatigue behaviors of twinning-induced plasticity steels fabricated by laser powder bed fusion

Twinning-induced plasticity (TWIP) steels fabricated by laser powder bed fusion (LPBF) were subjected to heat treatments at 400°C for 1 h and 800°C for 30 min, followed by high-cycle fatigue (HCF) testing. The results reveal that, despite the high…

Identification d'un modèle d'endommagement à l'échelle du pli composite grâce à des essais hors-axe d'orthotropie

Theidentification of the mechanical properties of composite materials is usually performed on specimens with well suited ply stackings. The industrialists designing CMCs parts face high production costs, and difficulties in producing tailor-suited…

Condition d’intégrabilité d’une loi d’hypoélaticité

We propose a geometric reformulation of hypoelasticity in terms of 1-forms (powers) on the manifold of the Riemannian metrics. From this reformulation, we establish a new necessary condition for the integrability of an hypoelasticity law, similar to…

Modélisation simplifiée de l'usure dans les liaisons à contact conforme – Application aux aubes à calages variables

Mastering engine maintenance is a key issue for airline companies. To avoid aircraft being grounded for extended and costly periods, it is strategically important to anticipate maintenance cycles, and therefore the wear of systems. In this context,…

Vers une nouvelle stratégie PGD pour la simulation numérique de structures élancées

Effective models for slender structures derived from well-known theories are justified within the limit of a small thickness, and may therefore prove limited for intermediate slenderness. On the other hand, direct 3D simulation of such structures is…
