A transmission electron microscopy (TEM) study using weak-beam imaging has been addressed in order to assess the microstructure of NiAl (100) single-crystals subsequently to irradiation at room temperature with 700 keV nickel ions up to 10(15) cm(-2) or 1. ...
Three-dimensional numerical simulations are performed to investigate the dynamic tensile properties of ceramics, using explicit dynamic FEM and cohesive element techniques. A micro-cracking model considering the stochastic distribution of internal defects ...
Using 3D finite element modelling, the present work investigates the coupling effect between superconducting filaments induced by an externally applied varying magnetic field. The considered geometry consists of two superconducting filaments separated by a ...
This paper presents the modeling strategy developed for the design of a planar solid oxide fuel cell repeat element. Design goal are to reach good performance (power density) and reliability (ie. limit risk of failure and degradation). This challenging pro ...
Magnetoconductance across permalloy/InAs(2DES)/permalloy double junctions in the ballistic limit is examined within the transfer-matrix formalism. We take into account Rashba spin–orbit interaction in the semiconductor as well as oblique modes in devices o ...
Optimization criteria for the representability of numerical models for the estimation of relative reactivity changes, due to localized perturbations in boiling water reactor (BWR) lattices, have been theoretically developed and tested. The validity of the ...
In typical power applications, Bi-2223 conductors carrying ac current will be subjected to external magnetic fields, whose orientation and conductor’s geometry are of major significance for the ac loss magnitude. This paper investigates the influence of th ...
This paper presents the application of spectral element methods to simulate the time-dependent flow of viscoelastic fluids in non-trivial geometries using a closed-form differential constitutive equation. As an example, results relative to the flow of a FE ...
We present an accurate and self-consistent technique for computing the electromagnetic held in scattering structures formed by bodies embedded in a stratified background and extending infinitely in one direction (two-dimensional geometry), With this fully ...
We have measured the giant magnetoimpedance (GMI) of microstructured Co-based Metglas (R) 2714a amorphous magnetic ribbons. Before micropatterning, the amorphous ribbons were chemically thinned or polished, to study the influence of sample thickness and su ...
