TITLE: Analytical and discrete element numerical modeling of ceramic sintering made by additive manufacturing
ACADEMIC: 3 years Phd – october 2021 – IRCER/CEA laboratories – Limoges city in France
OBJECTIVES: This study, which is a collaboration between the IRCER (Institute of Research on Ceramics – UMR CNRS 7315) and the CEA Le Ripault, proposes to develop a model of the sintering behavior of a ceramic object with a specific porous architecture using the Discrete Element Method (DEM). Indeed, sintering involves complex phenomena such as rigidification, densification or granular coarsening, which depend on the granular packing. A key scale to understand these complex phenomena is the meso-structure, which involves a few thousand of grains interacting through mechanical contacts (at the beginning of sintering), gradually giving way to the formation of bridges (necks) between grains during sintering. The discrete element approach allows to predict in a natural way these granular rearrangements from the fine knowledge of the driving forces governing the interaction between grains. Particular attention will therefore be paid to the choice of these micromechanical interaction laws between the grains, which must be capable of representing the consolidation and densificationkinetics. These numerical developments will be carried out within the discrete element code GranOO co-developed by the IRCER laboratory. It will then be necessary to develop a numerical approach capable of simulating the material transport paths involved in the creation of bridges between particles and to predict the apparent thermo-mechanical properties in a multi-scale approach.

We are looking for a competent Research Assistant (PhD Candidate) for our newly funded DFG project. The objective of the project is to evaluate the application of 3D printing in geomechanics with ultimate goal of understanding the mechanical and deformational characteristics of a rock mass with complex non-persistent discontinuities (DFNs). The research involves systematic laboratory testing on printed samples as well as subsequent calibration/verification using advanced numerical modelling. The funding allows us to hire a PhD student. The duration of the project is three years, starting in September 2021.
Application deadline: April 30th, 2021
