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…

Experiments, modelling and analysis of fretting fatigue for Inconel 718 and Ti-6Al-4V under time-varying contact normal load at room and high temperature

This work has been developed within the scope of a joint PhD agreement between the University of Paris-Saclay (UPS) and the University of Brasilia (UnB). The scientific context of the thesis has been chosen to try to provide data and solutions for…

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…

On two simple virtual Kirchhoff-Love plate elements for isotropic and anisotropic materials

Abstract The virtual element method allows to revisit the construction of Kirchhoff-Love elements because the $$C^1$$ C 1 -continuity condition is much easier to handle in the VEM framework than in the traditional Finite Elements methodology. Here…

From bi-dimensional discrete model to anisotropic damage model: a feasibility study

This study investigates using a discrete model (explicitly representing micro-cracking) as a "virtual test machine". Anisotropic damage models often require complex experiments to be formulated and identified. Discrete models could reduce the…
