Theoretical and numerical modeling of ultrasonic scattering in polycrystalline materials

The strong interaction between the polycrystalline microstructure and elastic waves makes it challenging to fully understand and master the relationship between ultrasonic grain scattering and the crystallographic and morphological characteristics…

Theoretical and numerical comparison of the elastic ultrasonic wave scattering in polycrystalline materials with fiber texture

The physics of the elastic ultrasonic wave scattering is of interest for the non-destructive Laser-Ultrasonics (LU) technique to characterize polycrystalline materials. Generally, polycrystalline media are composed of multiple anisotropic single…

Stress intensity factor determination along a kinked crack path by DIC analyses

Sharp kinks may be observed under shear loading or in materials containing weak directions, such as those produced by additive manufacturing. A better understanding of the fracture of these materials, both theoretically and experimentally, is…

Condition d'intégrabilité d'une loi d'hypoélaticité

Nous proposons une reformulation géométrique de l'hypoélasticité en terme de 1-formes (puissances) sur la variété des métriques riemanniennes. A partir de cette reformulation, nous établissons une nouvelle condition nécessaire d'intégrabilité d'une…

Augmented DIC and FE Analyses: A Two-Field Approach to Damage Localization

The prediction of localized phenomena is still challenging. In particular, running an entirely consistent simulation with experimental observations is delicate. It is proposed that FE simulations on fine meshes be augmented with experimentally…

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…

A new Neural Network-based methodology for multi-level topology optimisation in structural problems

The optimisation of high-resolution trabecular structures is crucial for various industrial applications due to their resilience to unexpected loads. Current topology optimisation (TO) approaches face challenges like high computational costs and…

Formulation Covariante du Couplage Electro-Magneto-Mécanique

Le présent travail porte sur la reformulation du couplage électro-magnéto-mécanique à partir du cadre de la relativité générale, pour les milieux continus non conducteurs. Un élément central de ce travail est l'introduction d'un lagrangien de…

A step toward flow simulation through cracks in beam-particle models

Crack characterization in reinforced concrete structures, such as the containment walls of 1300 MWe nuclear power plants, is critical for accurately estimating air leakage. Traditional modeling strategies, such as Poiseuille's law applied to a…
