v1.02.011 PERFE01 — Non-regression of the homogenized BZ calculation of the PERFECT platform

Summary:

This test makes it possible to validate the commands used by the PERFORM platform, which makes it possible to simulate the effects of irradiation on reactor components. We are interested here in tank steel.

We consider a volume element to which an imposed deformation is applied. The material consists of a polycrystal with 30 monocrystalline phases, homogenized by the Berveiller-Zaoui (BZ) method.

Modeling A tests the average stresses and deformations obtained for an imposed deformation.

of \(\text{1 \%}\) for phenomenological behavior.

Modeling B tests the average stresses and deformations obtained for an imposed deformation.

of \(\text{1 \%}\) for DD_CC behavior..
