Damage, Opening and Sliding of Grain Boundaries
This paper presents an approach to the modeling of damage, opening and sliding of the grain boundaries in zircaloy submitted to stress corrosion cracking. Grain boundaries are seen as a continuous material. The grains are modeled by a model of crystal viscoplasticity. Environement is taken into account by means of weak coupling between diffusion and mechanics. 2D and 3D finite element computations for polycrystalline aggregates are presented.
