Ceramic powder-based hybrid binder jetting system, Procédé hybride de fabrication additive par projection de liant sur lit de poudre céramique

Qirong Chen

Binder jetting (BJ) is an additive manufacturing process in which powders are selectively joined by a binder to reproduce an object layer by layer. Despite numerous advantages, BJ is still plagued by two main limitations. Ceramics printed with BJ remain very porous after sintering and exhibit poor..., Le Binder Jetting (BJ) ou projection de liant est un procédé de fabrication additive dans lequel des poudres sont sélectivement liées par un liant pour reproduire un objet couche par couche. Malgré ses nombreux avantages, le BJ souffre encore de deux limitations principales. Les céramiques...

On Levi flat hypersurfaces with transversely affine foliation

Séverine Biard, Masanori Adachi

We prove the non-existence of real analytic Levi flat hypersurface whose complement is 1-convex and Levi foliation is transversely affine in a compact Kähler surface.

Deep Gaussian Process for the Approximation of a Quadratic Eigenvalue Problem: Application to Friction-Induced Vibration

Jeremy Sadet, Franck Massa, Thierry Tison, El-Ghazali Talbi, Isabelle Turpin

Despite numerous works over the past two decades, friction-induced vibrations, especially braking noises, are a major issue for transportation manufacturers as well as for the scientific community. To study these fugitive phenomena, the engineers need numerical methods to efficiently predict the...

Existence results for the $\mathbf{A}-\varphi-\mathbf{B}$ magnetodynamic formulation of the Maxwell system with skin and proximity effects

Emmanuel Creusé, Serge Nicaise, Ruth V Sabariego

The $\mathbf{A}-\varphi-\mathbf{B}$ magnetodynamic Maxwell system given in its potential and space-time formulation is a popular model considered in the engineering community. It allows to model some phenomena such as eddy current losses in multiple turn winding. Indeed, in some cases, they can...

Wavenumber explicit convergence analysis for finite element discretizations of time-harmonic wave propagation problems with perfectly matched layers

Théophile Chaumont-Frelet, Dietmar Gallistl, Serge Nicaise, Jérôme Tomezyk

The first part of this paper is devoted to a wavenumber-explicit stability analysis of a planar Helmholtz problem with a perfectly matched layer. We prove that, for a model scattering problem, the H1 norm of the solution is bounded by the right-hand side, uniformly in the wavenumber k in the highly...

Exponential and polynomial stability results for networks of elastic and thermo-elastic rods

Alaa Hayek, Serge Nicaise, Zaynab Salloum, Ali Wehbe

<p style='text-indent:20px;'>In this paper, we investigate a network of elastic and thermo-elastic materials. On each thermo-elastic edge, we consider two coupled wave equations such that one of them is damped via a coupling with a heat equation. On each elastic edge (undamped), we...

Assembly of SBA-15 into hierarchical porous monoliths replicating polymeric scaffolds

Rıdvan Yildiz, Yannick Lorgouilloux, Jérémy Dhainaut, Carmen Ciotonea, Jean-Philippe Dacquin, Sébastien Royer, Christian Courtois

This study reports the preparation of highly porous, SBA-15-based monolithic materials with pore sizes spanning over four scales (micro-/meso-/small macro-/large macro-pores). Two approaches were explored. The first one involves the preparation of PMMA scaffolds obtained from chemically-bonded...

The influence of the physical coefficients of a Bresse system with one singular local viscous damping in the longitudinal displacement on its stabilization

Mohammad Akil, Haidar Badawi

In this paper, we investigate the stabilization of a linear Bresse system with one singular local frictional damping acting in the longitudinal displacement, under fully Dirichlet boundary conditions. First, we prove the strong stability of our system. Next, using a frequency domain approach...
