**v6.04.116** SSNV116 — POLYCRISTAL steel UMAT law — benchmark with Abaqus
==========================================================================

**Summary:**

Within SINDRI research project [:ref:`4 <4>`] a benchmark between Abaqus and code_aster has been developed based on a Crystal Plasticity Finite Element (CPFE) behaviour law using the formalism of UMAT [:ref:`1,2 <1,2>`].

The geometry is a 1x1x1 cube derived from DREAM3D software which produces synthetic EBSD grains orientations. The sample is submitted to a fixed displacement to one end and clamped on another end.

With this test it is shown that code_aster results compares well to Abaqus.
