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…

First approach of a mixed domain decomposition method for magnetostatic simulation of rotating machines

In this work, a mixed domain decomposition method (LATIN) is proposed to improve the efficiency of magnetostatic simulation of rotating machines. This strategy relies on a decomposed formulation of the problem considering both primal and dual fields…

An orthotropic damage model with internal sliding and friction for masonry-like material

Quasi-brittle materials like masonry exhibit mechanical properties and develop nonlinearities that are mainly driven by their joints. In the present work, a Continuum Damage Mechanics point of view is considered to describe the macroscopic behavior…

Impact of grinding process on the mechanical behavior of CVI-SiC/SiC tubes for nuclear application

SiC/SiC composites are promising candidates for nuclear fuel cladding due to their outstanding mechanical resistance and properties at high temperatures (>1200°C). During the manufacturing process, a grinding phase of both the external and…

DVC Analyses to Study Deformation and Damage mechanisms of Teak in Torsion

Wood is a material with anisotropic elastic properties at the macroscale. In the present work, a sample made of Beninise teak was subjected to in situ torsion. DVC analyses were run at the mesoscale to measure displacement fields. The corresponding…
