Cohesive properties of refractory castable at 600°C: Effect of sintering and testing temperature

This paper aims to evaluate cohesive properties for an alumina refractory with mullite-zirconia aggregates from wedge splitting tests (WST), and to assess their sensitivity to sintering and testing temperature. Five experiments were analyzed of…

Identification of Cosserat elastic overall media of quasi-periodic lattices

For a few years, the interest in architectured materials has grown since they enable to reach new zones of Ashby diagrams. Quasi-periodic lattices are a class of porous materials that appear locally disorganised but are highly deterministic, as…

Data-based Model Updating, Selection, and Enrichment using the Modified Constitutive Relation Error Concept

In the context of computational engineering, physical systems are classically represented by a mathematical model which can be picked in a hierarchical list of possible models, with increasing complexity, and which is then numerically processed to…

Insights into a dual-phase steel microstructure using EBSD and image-processing-based workflow

Quantitative metallography to understand the morphology of different crystallographic phases in a material often rests on the segmentation and classification of electron backscatter diffraction (EBSD) maps. Image analysis offers rich toolboxes to…

Flambage des nids d'abeilles en bicompaction

Les matériaux architecturés présentent de hautes caractéristiques spécifiques grâce à leurs mésostructures élancées (poutres, plaques et coques). La nature élancée de ces géométries favorisent l’apparition de flambage à l’échelle d’une ou plusieurs…

Recent Fourier continuation-based solvers for time-dependent problems in solids, fluids & their interactions

This contribution overviews a spectral methodology for the numerical solution of partial differential equation systems governing various mechanical wave propagation problems. Based on a Fourier continuation (FC) approach for the accurate…

Modèle simplifié de liaison boulonnée avec frottement et plasticité pour la simulation de la tenue des assemblages en calcul des structures

Le dimensionnement des assemblages boulonnés par un modèle éléments finis volumiques est généralement coûteux en temps de mise en données et de calcul. Un modèle simplifié de liaison boulonnée basé sur des paramètres de conception (précharge,…
