Reference quantities and results
------------------------

The displacement of the :math:`B` node following :math:`X` (DEPL) and the force applied to the test piece (REAC_NODA) were calculated.

**For modeling A:**

A comparison is made with two different calculations:


* a previous execution of Code_Aster with law CZM_TRA_MIX, this is a non-regression test case;


* a previous execution of Code_Aster where the ductile break is modeled with the Rousselier model by law ROUSS_PR.

In the case of modeling with the Rousselier model, the parameters used for this model are as follows: :math:`D\mathrm{=}2`, :math:`{\mathit{SIGM}}_{1}\mathrm{=}460` and :math:`\mathit{f0}\mathrm{=}\mathrm{0,0005}`

**For B modeling:** we only perform non-regression tests.
