5. D modeling#

5.1. Characteristics of modeling#

Homogenized polycrystalline behavior. On the material point. 30 grains of fixed orientations.

The law used is Polycrystal_mc.mfront

5.2. Tested sizes and results#

The solution obtained with the Mfront behavior and that obtained with the behavior POLYCRISTAL is compared, by testing the maximum of the relative difference of the following components:
