Corrosion fatigue mechanisms of high-strength steel wires in the presence of various aggressive ions

This work focuses on the corrosion fatigue of high-strength steel wires with diameters of 200 μm. The fatigue load consists of a bending rotation with a stress amplitude between 1300 MPa and 700 MPa. Various solutions at pH 6 containing either…

Geometry-agnostic model reduction with GNN-generated reduced POD bases and boosted PGD enrichment for (non)linear structural elastodynamics

This contribution proposes a new and significantly enhanced extension of a recently-introduced hybrid Graph Neural Network (GNN)-based reduced-order modeling approach for the numerical solution of time-dependent partial differential equations on non…

Cinématiques des milieux généralisés et repères mobiles

This work presents a unified geometrical framework for modeling generalised continua in finite strains : in any dimension (rods, shells, 3D media), in any micromorphic theory of order one (micromorphic, Cosserat, micro-dilatation, etc) and in any…

Data-driven Metamodels for Failure Analysis of Power Electronic Modules

This work presents a thorough analysis of machine learning (ML)-based metamodels to assess the reliability of power electronic modules (PEMs). Accurate lifetime prediction pipelines often require frequent updates of the mechanical state of PEMs…

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…
