In-situ strain induced martensitic transformation measurement and consequences for the modeling of medium Mn stainless steels mechanical behavior

This work aims at studying the control of medium manganese austenitic stainless steels' mechanical behavior and austenite to martensite transformation via chemical composition. Six grades of austenitic stainless steel were cast with chemical…

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…

Modelling of a PsD hybrid test on a RC column/beam junction combining a multifibre beam model and a POD-ROM approach

In this paper, a pseudo dynamic (PsD) hybrid experimental setup allows for assessing the nonlinear behaviour of a reinforced concrete (RC) column/beam junction under earthquake is proposed. The specimen is linked to a numerical substructure made of…

Une approche multi-échelle d'une méthode de décomposition de domaine mixte pour la simulation magnétostatique 3D

Pour répondre aux besoins numériques d'optimisation de machines tournantes, nous proposons d'adapter la méthode LATIN avec sous-structuration à la résolution des équations de la magnétostatique en conservant les aspects mixte et multi-échelle de la…
