Robust calibration of a multi-physics model of an offshore wind turbine using in situ data

The aim of the work in the thesis is to propose a robust method for data assimilation to be used with the measurements available from EDF's farms, using fluid-structure interaction models and in situ data. The scientific problematic is part of…

An introductory review on a posteriori error estimation in Finite Element computations

This article is a review on basic concepts and tools devoted to a posteriori error estimation for problems solved with the Finite Element Method. For the sake of simplicity and clarity, we mostly focus on linear elliptic diffusion problems,…

Seismic hazard analysis with a Fourier Neural Operator (FNO) surrogate model enhanced by transfer learning

Seismic hazard analyses in the area of a nuclear installation must account for a large number of uncertainties, including limited geological knowledge. It is known that some geological features can create site-effects that considerably amplify…

Blast protection with fluids

Following the detonation of an explosive charge, such as a buried mine or an improvised explosive device, under a vehicle floor, two main effects occur: the rupture or deformation of the vehicle floor due to the loading transmitted by the blast wave…

Understanding of selective oxidation of Fe-Mn binary alloys during continuous annealing through X-ray photoelectron spectroscopy

Selective oxidation of Fe-Mn alloys was characterizied through X-ray photoelectron spectroscopy and scanning/transmission electron microscopy during industrial continuous annealing (in an atmosphere of N2 –5 vol.% H2 with traces of water at 800 °C)…

Statistical Analysis of the Ultimate Strength of Filaments, Tows and Minicomposites

The present paper investigates the failure of SiC and alumina-fiber-reinforced minicomposites in relation to the strength distributions of filaments, and the failure behavior of the reinforcing dry tows. The strength data are measured on single…

Etude multi-échelles pour la compréhension des phénomènes de fragilisation par les métaux liquides : cas de laitons α en présence de l’eutectique Ga-In

Lorsqu’il est en présence de métal liquide, un alliage métallique ductile à l’air peut être sen-sible à la fragilisation par les métaux liquides (FML), ce qui se traduit par une perte de ductili-té pouvant provoquer une rupture fragile partielle ou…
