Hybrid additive/subtractive manufacturing system to prepare dense and complicated ceramic parts

Fabrice Petit, Qirong Chen, Enrique Juste, Marie Lasgorceix, Anne Leriche

As the conventional binder jetting method is limited in terms of achievable density and finish surface, a new concept of hybrid subtractive/additive manufacturing system has been recently developed. The system relies on a modified binder jetting machine which integrates a slurry-based deposition…

MULTIPLE BOUNDED VARIATION SOLUTIONS FOR A PRESCRIBED MEAN CURVATURE EQUATION WITH NEUMANN BOUNDARY CONDITIONS

Alberto Boscaggin, Francesca Colasuonno, Colette De Coster

We prove the existence of multiple positive BV-solutions of the Neumann problem - (u'/\sqrt{1+{u'}^2})' = a(x)f (u) in (0, 1), u (0) = u (1) = 0, where a(x) > 0 and f belongs to a class of nonlinear functions whose prototype example is given by f (u) = −λu + u^p, for λ &gt…

Effect of spray drying treatment on the optical properties of Mg–Al spinel ceramics

Robin Stocky, Judith Boehmler, Sébastien Lemonnier, Pierre Gibot, Yannick Lorgouilloux, Anne Leriche

In recent years, Mg–Al spinel ceramic has been in the spotlight due to its large transparency range and goodmechanical properties. The aim here, was to control the state of agglomeration of powder to improve densifi-cation behaviour and consequently optical and mechanical properties of the ceramics…

Guaranteed Quantity of Interest Error Estimate Based on Equilibrated Flux Reconstruction

Zuqi Tang, Suyang Lou, Abdelkader Benabou, Emmanuel Creusé, Serge Nicaise, Julien Korecki, Jean-Claude Mipo

The quality of a local physical quantity obtained by the numerical method, such as the finite element method (FEM), attracts more and more attention in computational electromagnetism. Inspired by the idea of goal-oriented error estimate given for the Laplace problem, this work is devoted to a…

Control of the Microstructure in Ceramics

Anne Leriche, Stuart Hampshire, Francis Cambier

Ceramic materials are commonly fabricated by powder processing and a subsequent heat treatment, which results in the elimination of about 40 vol% of porosity during the sintering step. The densification occurs at high temperature allowing atom diffusion in the solid state or through a liquid phase…
