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,…

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…

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…

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…

Inverse identification of pipeline steel mechanical state by means of coupled magnetic measurements and artificial neural networks

Artificial neural networks are widely used to develop models able to predict properties of interest by learning and establishing relationships between inputs and outputs of a system. It is particularly relevant for the inversion process in the…

UNDERSTANDING THE INFLUENCE OF MANUFACTURING DEFECTS ON THE TENSILE BEHAVIOR OF SIC/SIC FILAMENT WOUND TUBES FROM A UNIDIRECTIONAL COMPOSITE MODEL

SiC/SiC ceramic matrix composites are promising cladding candidates to improve the accident tolerance of the fuel in pressurized water reactors. Indeed, their excellent mechanical properties at high temperatures (above 1200°C) would give them…

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…
