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…

Experimental and numerical investigation of drying rate impact on moisture loss, exchange coefficient and drying shrinkage of cement paste

Assessment of moisture content evolution and drying shrinkage is important for the long-term operation of large concrete structures. This paper evaluates the impact of size and boundary conditions in predicting mass loss and drying shrinkage of…

Investigation of Lattice Plasmon Modes in 2D Arrays of Au Nanoantennas

The coupling of gold nanoantennas (AuNAs) in the arrangement of monomers in bidimensional gratings is investigated both experimentally and numerically. The influence of edge diffraction, corresponding to the grazing propagation of specific…

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,…

Transient Propagation and Scattering of Quasi-Rayleigh Waves in Plates: Quantitative comparison between Pulsed TV-Holography Measurements and FC(Gram) elastodynamic simulations

We study the scattering of transient, high-frequency, narrow-band quasi-Rayleigh elastic waves by through-thickness holes in aluminum plates, in the framework of ultrasonic nondestructive testing (NDT) based on full-field optical detection…

A Reduced Model Based on Proper Generalized Decomposition for the Fast Analysis of IGBT Power Modules Lifetime

Abstract A reduced weakly-coupled thermo-mechanical model based on the proper generalized decomposition method was developed for the numerical analysis of power modules. The employed model reduction method enabled us to obtain, in a preliminary…

CONCRETE DRYING KINETICS: DEVELOPMENT OF AN ACCELERATED DRYING PROTOCOL IN FIRE TESTINGS

This work proposes an accelerated drying protocol that allows reaching a hydric and mechanical state representative of normal service conditions while optimizing the storage time of the specimen before the fire resistance test. The temperature and…

Experimental modeling of burnt oil shale impact towards ASR

The alkali-silica reaction (ASR) is a civil engineering issue that can be inhibited using supplementary cementitious materials such as burnt oil shale. Furthermore, these allow an improvement of the properties of the concrete as increasing density…

Local-global DVC analyses confirm theoretical predictions for deformation and damage onset in torsion of pantographic metamaterial

Pantographs are a special class of metamaterials that do not obey theories of first gradient continua. In the present work, a pantographic metamaterial was printed and subjected to in situ torsion. The experiment was designed in order to investigate…
