1. Polycrystal behavior
In this section, we will first distinguish the case of structures made up of two to a few dozen grains, before tackling the problem of the mechanical behavior of the polycrystalline volume element (VER).
1.1 Calculation of multicrystalline aggregates
The mechanical response of bi- and multicrystals can be calculated by assigning to each grain the laws of crystalline plasticity described in the article and assigning each its precise crystallographic orientation. Conditions of continuity of displacement and tensile vector are imposed at grain boundaries. Grain boundaries can, however, be the site of more complex behavior, which will be discussed in ...
