Investigation of the internal structure of flax fibre cell walls by transmission electron microscopy

Anthony Thuault, Bernadette Domengès, Isabelle Hervas, Moussa Gomina

The development of the use of flax fibre as reinforcement of eco-friendly composite materials requires a good knowledge of its hydrothermal and mechanical behaviours. To this end the fibre internal structure must be finely investigated. Transmission electron microscopy was used to analyse the...

ACTIVE LEARNING BY VIRTUAL PROTOTYPING TECHNIQUE

Mariana Fratu, Jean-Paul Becar, Jean-Charles Canonne, Aurel Fratu

In this paper, the development of virtual prototypes models and their testing for active learning support is described. The personalized virtual applications selected by a tutor are used directly for performing active learning at the university's separated workplace. When using the virtual...

Source identification for the wave equation on graphs

Sergei Avdonin, Serge Nicaise

We consider source identification problems for the wave equation on graphs. The main advantage of our approach is its locality. Our algorithm reduces essentially to the resolution of linear integral Volterra equations of the second kind and is new even for an interval.

Space-time residual-based a posteriori estimator for the A-phi formulation in eddy current problems

Roberta Tittarelli, Yvonnick Le Menach, Emmanuel Creusé, Serge Nicaise, Francis Piriou, Olivier Moreau, Olivier Boiteau

In this paper, an a posteriori residual error estimator is presented for the 3-D eddy current problem modeled by the space-time A - φ potential formulation. It is solved by the finite element method in space and the backward Euler scheme in time. Once the reliability as well as the efficiency of...

Thermal conductivity modeling of Alumina/Al functionally graded composites

Christine Pelegris, Nabil Ferguen, Willy Leclerc, Yannick Lorgouilloux, Stéphane Hocquet, Olivier Rigo, Mohamed Guessasma, Emmanuel Bellenger, Christian Courtois, Véronique Lardot, Anne Leriche

This paper describes a new manufacturing process for producing functionally graded ceramic‐metal composites with anisotropic properties for thermal management in automotive engine blocks. These composites are elaborated by producing a porosity gradient within an alumina matrix, subsequently...

A mixed DG method for folded Naghdi's shell in Cartesian coordinates, Une méthode de Galerkin discontinue mixte pour une coque de Naghdi pliée en coordonnées cartésiennes

Serge Nicaise, Ismail Merabet

In this Note, a mixed formulation is proposed to solve Naghdi's equations for a thin linearly elastic shell. The unknowns of the problem are the displacement of the points of the middle surface, the rotation field of the normal vector to the middle surface of the shell and a Lagrange..., Dans cette Note, nous proposons une méthode mixte pour résoudre les équations du modèle de Naghdi de coques linéairement élastiques. Les inconnues du problème sont le déplacement des points de la surface moyenne, le vecteur de rotation de la normale à la surface moyenne et un multiplicateur de...

Generalizations of Poisson Structures Related to Rational Gaudin Model

Dimitri Gurevich, Vladimir Roubtsov, Pavel Saponov, Zoran Škoda

<p>The Poisson structure arising in the Hamiltonian approach to the rational Gaudin model looks very similar to the so-called modified Reflection Equation Algebra.&nbsp; Motivated by this analogy, we realize a braiding of the mentioned Poisson structure, i.e. we introduce a ”braided...

Sweeping process by prox-regular sets in Riemannian Hilbert manifolds

Frédéric Bernicot, Juliette Venel

In this paper, we deal with sweeping processes on (possibly infinite-dimensional) Riemannian Hilbert manifolds. We extend the useful notions (proximal normal cone, prox-regularity) already defined in the setting of a Hilbert space to the framework of such manifolds. Especially we introduce the...

Points massiques, hyperbole et hyperboloïde à une nappe

Jean-Paul Becar, Lionel Garnier, Lucie Druoton

Les courbes de Bézier rationnelles quadratiques jouent un rôle fondamental pour la modélisation d'arcs de coniques propre. Cependant, lorsque les deux points extrémaux de l'arc ne sont pas sur la même branche d'une hyperbole, l'utilisation des courbes de Bézier classiques est...
