1 Postdoctoral Fellowship for the project entitled “Dynamic Recrystallization Modeling By Field Dislocation Mechanics And Level-Set Approaches” in France | Centre for Material Forming (CEMEF)

Postdoctoral fellowship is available at CEMEF for the project entitled “Dynamic Recrystallization Modeling By Field Dislocation Mechanics And Level-Set Approaches”. This is a 24 months post-doctoral position. The first year will be spent in LEM3 (Metz) whereas the second year will be spent in CEMEF MINES ParisTech (Sophia Antipolis). The recruited post-doctoral fellow will conduct the modeling part of the DREAM project with regular interactions between the research teams of LEM3 and CEMEF. He will also interact with colleagues performing experiments in LGGE (Grenoble) and Géosciences Montpellier. During his first year, the recruited candidate will essentially develop a field dislocation mechanics (FDM) model. FDM is a continuum approach of elasto-plasticity that deals with longrange correlations and internal stresses due to dislocations arrangements and with plasticity mediated by dislocation transport. It is therefore well adapted to simulate nucleation, but is limited to small polycrystals (a few grains). In particular, the correct description of the interfaces (grains, sub-grain boundaries) will constitute a key point of the simulations in order to handle realistic dislocation distributions. During his second year, the post-doctoral fellow will work on a Crystal Plasticity Finite Element Model (CPFEM) combined with a full field approach based on a level set description of the grains (FFALS) in order to model DRX in large polycrystals. The CPFEM approach will be appended by FDM outputs in order to implement continuity conditions at interfaces and driving forces for grain boundary motion. By progressively linking the inputs/outputs of the two models, the candidate will estimate the level of complexity needed to build a predictive model of DRX in realistic polycrystalline configurations.
