2. Benchmark solution

2.1. Reference quantities and results

The displacement of the \(B\) node following \(X\) (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: \(D\mathrm{=}2\), \({\mathit{SIGM}}_{1}\mathrm{=}460\) and \(\mathit{f0}\mathrm{=}\mathrm{0,0005}\)

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