Damage, Opening and Sliding of Grain Boundaries

Musienko, A. / Cailletaud, G. / Diard, O.

Abstract 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.
