Mechanics of materials

Identication of the interfacial fracture energy at high temperature of an environmental barrier coating on a ceramic matrix composite

In the present work, the interface fracture energy between a SiC/SiC ceramic matrix composite and its environmental barrier coating is assessed at 1000°C. Four-point flexural tests with no precrack were conducted inside a furnace to propagate stable…

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…

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…

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…

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…
