Optimisation d'un procédé de soudage par difusion à l'état solide pour réaliser des circuits imprimés : Application au système Au-Cu-Sn

A solid-state diffusion bonding technology, called thermodiffusion, has been developed to miniaturizePCB. A promising configuration where thin layers of gold and tin are coated on the two copper layers to be joined has been chosen. The…

Évaluation du coefficient de diffusion des chlorures dans le béton armé sous chargement mécanique

In service conditions, reinforced concrete structures are cracked, which enable the chloride ingress and diffusion and could initiate steel reinforcement corrosion. This project aims to measure the impact of both micro- and macro- cracks, obtained…

Development of a multi-scale approach for modeling cast duplex stainless behavior

Monitoring pressurized water reactors components is of interest in long-term operation of nuclear power plants. Components made out of cast duplex stainless steel are subjected to aging when held at their operating temperature. In the long run,…

Reduced-order models for aeronautics based on the LATIN-PGD method within non-linear industrial Simcenter Samcef software

A weakly-invasive version of the LATIN-PGD method is described to build reduced-order models within general-purpose industrial finite element software, such as Simcenter Samcef™ developed by Siemens Digital Industries Software. The originality of…

Etude expérimentale de la méthode des bielles-tirants sur des zones massives en béton armé par l'analyse de déformation pour des chargements complexes

The strut-and-tie method is the recommended design method for massive structures or D-zone in codes and standards. The application of the method is usually done by hand by the designer.It is the subject of load history that is the focus of the work…

Mesh generation of complex three‐dimensional geometries for beam‐particle modeling of fracture

In this article, we propose a three-dimensional meshing algorithm for discrete models combining the lattice approach with the polyhedral particle approach. Our aim is to be able to leverage readily available, well-supported meshers to handle various…

Multifunctional Properties of Polyvinylidene-Fluoride-Based Materials: From Energy Harvesting to Energy Storage

Organic ferroelectrics are increasingly important due to their complementary properties to classical, inorganic ferroelectrics. Flexibility, chemical resistance, scalability, high breakdown fields, and biocompatibility are attractive for many…

Modélisation du couplage magnéto-élastique dans les milieux solides à symétrie cubique

The performance of electrical machinesis largely related to the magnetic behavior of theferromagnetic materials they are made of. Takinginto account the magneto-mechanical coupling isone of the possible ways of progress in this field.The strongly…
