Offre de Thèse : Finite element modeling of Hot Isostatic Pressing at the mesoscopic scale

Société : CEMEF

Le CEMEF, Centre de Mise en Forme des Matériaux (CEMEF) de Mines ParisTech basé à Sophia Antipolis, possède une expertise dans le domaine de la caractérisation et de la modélisation de la rupture en mise en forme et en service ainsi que des compétences en métallurgie et mise au point d’essais thermomécaniques.

Description du poste

In terms of microscale modeling, the present project aims at developing advanced numerical techniques for taking into account,
in 2D/3D simulation context, all the key physical phenomena that
take place during HIP process from start to finish. Within a parallel computing context, simulations will be firstly based on a levelset interface capturing technique in a FE framework and Eulerian
formalism [1,2]. Combined with an anisotropic mesh adaptation
strategy, this numerical approach will be used to describe with
accuracy the granular packing geometry, particle interface evolution, grain interface evolution but also the second phase particle
populations and their evolution. Such simulations in a context of
a new front-tracking methodology will also be considered [3]. The
developments will be validated thanks to pre-existing experimental and numerical data concerning the evolution of particle/grain
boundary interfaces available in CEA Grenoble.
