Résumé

This paper describes a level-set framework for the full field modeling of dynamic and post-dynamic recrystallization in a 3D polycrystalline material submitted to large deformation. Topological evolutions are simulated based on a kinetic law linking the velocity of grain boundaries to the thermodynamic driving forces. Recrystallization is modeled by coupling a level-set approach to phenomenological laws describing strain hardening and nucleation. The proposed formalism enables to reach outstanding dynamic recrystallization computations in a front-capturing finite element framework comparatively to the state of art.
