Offre de Thèse : New insights in the reduced mobility description for the modeling of grain growth and recrystallization at the polycrystalline scale

Postée le 19 jan.

Lieu : sophia antipolis · Contrat : CDD · Rémunération : 27.7k€ €

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

Moreover, the discussion of the classical kinetic equations used at
the mesoscopic scale to describe the relation between the driving pressures acting on the grain boundaries and their resulting
motion is more and more discussed [4,5]. This PhD will be dedicated to the enrichment of existing full-field front-capturing [6]
and front-tracking [7] methods to integrate some new capabilities
such as the use of a tensorial reduced mobility description, a better integration of torque terms in 2D and 3D and a disconnectionbased description of the involved mechanisms. The developments
will be validated thanks to pre-existing experimental and numerical data concerning the evolution of grain boundary interfaces
during recrystallization and related phenomena for different materials. They will also be integrated in the DIGIMU®

Profil recherché

Degree: MSc or MTech in Metallurgy or Applied
Mathematics. Skills: Numerical Modeling, Metallurgy, programming, proficiency in English, ability
to work within a multi-disciplinary team.
