Réduction et recalage de modèles d'un module de puissance : vers un jumeau numérique probabiliste pour la prédiction de durée de vie restante

Power electronic modules transform the electrical current from the grid to meet the requirements of electric motors. These components are essential to numerous electrical systems. During their operation, losses generate heat within the module,…

A review on fused deposition modeling materials with analysis of key process parameters influence on mechanical properties

Fused deposition modeling (FDM) also called fused filament fabrication (FFF) is the most used additive manufacturing (AM) technology. The growing impact of AM is due to its various advantages and its applicability to many domains. Many research…

Local characterization of stainless steel 17-4PH produced by material extrusion additive manufacturing: Influence of the post-treatment

This study focuses on the influence of porosities present in the stainless steel 17-4 PH made by material extrusion additive manufacturing (MEAM) process. A comparison is made at the sub-micron scale between an as-fabricated sample and a H900 post…

Numerical simulation of wave propagation in 3D basin models and their effects on nonlinear structures response

Sedimentary materials enclosed in basins modify the earthquake ground motion (EGM) characteristics by energy trapping, resonance and surface wave generation at the basin edge. Usually, these are defined as site effects and are considered by proxies…

Numerical Investigation of Echogenicity for 3D-Printed Tissue-Mimicking Material Toward the Development of Synthetic Organs' Digital Twins

This thesis explores the use of tissue-mimicking 3D-printed materials to create anatomical phantom twins. These twins are intended to provide sophisticated training stations for medical practitioners to rehearse patient-specific interventions. The…

Thermomechanical characterization and modeling of shape memory alloys - application on 26at%Nb-Ti

The behaviour of shape memory alloys is driven by a first-order solid-solid phase transformation taking place at microscopic scales (grain or sub-grain scale). Thanks to their atypical behaviour (shape memory and pseudo-elastic capacities), they are…
