v6.04.171 SSNV171 — Inter-comparison of MONOCRISTAL AND POLYCRISTAL behaviors

Summary:

The purpose of this test is to validate behaviors MONOCRISTAL and POLYCRISTAL by inter-comparison, in a particular situation: a single grain for MONOCRISTAL and a single phase for POLYCRISTAL. The crystalline behavior is of the type MONO_VISC1, MONO_CINE1, MONO_ISOT1 (Meric-Cailletaud).

The geometry processed is a material point, and the crystal is not parallel to the coordinate axes.

3 models make it possible to compare:

• MONOCRISTAL behaviors (various implicit integration algorithms, A and B models)

• single-grain MONOCRISTALet POLYCRISTAL behaviors, with explicit integration, as well as Weibull post-processing (C modeling).
