3D Full field modelling of recrystallization in a finite element framework – application to 304L
Résumé
This paper describes a level-set framework for the full field modelling of recrystallization and grain growth in a polycrystalline material. Topological evolutions are simulated based on a kinetic law linking the velocity of the boundaries to the thermodynamic driving forces. Dynamic recrystalli- zation is also modelled by coupling the level-set method to mean field laws describing strain harde- ning mechanism and nucleation criteria. The proposed formalism enables to reach outstanding massively multi-domain computations in a front-capturing finite element framework comparatively to the state of art.
