7. F modeling#

7.1. Characteristics of modeling#

Homogenized polycrystalline behavior DD_CFC. Material point. 30 grains of fixed orientations.

The law used is PolyCrystal DDCFC .mfront

7.2. Tested sizes and results#

We compare the solution obtained with the Mfront behavior and that obtained with the POLYCRISTAL behavior of type DD_CFC, by testing the maximum difference of the following components:

Relative Gap

Reference (Difference)

Absolute Tolerance
