Failure mechanism identification for multiaxially loaded woven composites using hybrid infrared-visible light correlation

This paper presents a detailed analysis of 3-mm thick woven glass fiber composite samples subjected to complex in-plane loading regimes. Three butterfly shaped samples, each with two V-notches in the gauge region, were tested under tensile, simple…

Three-dimensional crack reconstruction from Beam–Particle Model for CFD-based leakage assessment

Accurate crack characterization in reinforced concrete structures, such as the containment walls of 1300 MWe nuclear power plants,is essential for reliable air leakage estimation. The complexity of crack patterns—including their path, opening, and…

Towards a new PGD strategy for the simulation of slender structures

Effective models for slender structures derived from well-known plate (or shell) theories are justified within the limit of a small thickness, and may therefore prove limited for intermediate slenderness. On the other hand, direct 3D simulation of…

TRansformer pour Adapter l'existant : une approche multisCalairE et Systémique

Face à l’intensification des changements globaux liés aux processus d’urbanisation à l’échelle planétaire, la transformation de l’existant représente un défi crucial pour répondre aux enjeux contemporains et repenser les modes de conception,…

Multiscale modeling of twinning mechanism in polycrystalline 26at%Nb-Ti shape memory alloy

This article investigates the twinning mechanism in a polycrystalline 26at%Nb-Ti shape memory alloy, developed as a biocompatible alternative to NiTi. After metallurgical and mechanical characterization, tensile tests reveal that only the {332} $…

Graph Transformer Transferability for Flood Scusceptibility mapping in contrasting regions

Graph Transformers have demonstrated considerable promise for spatial prediction tasks, yet their capacity to generalize across contrasting flood regimes remains poorly understood. This study examined whether a GT model trained on the French Riviera…

AI surrogate models for lifetime prediction in power electronic modules

Reliability assessment of power electronic modules (PEMs) traditionally relies on counting methods to decompose complex mission profiles (MPs) into equivalent loading cycles, followed by a cumulative damage rule to estimate fatigue life. While…
