2. Benchmark solution

This test case is a case of non-regression. This is a study, which quickly goes from a weakly damaged state to a state of rupture (damage equal to 1).

Loads are not analytical. The values of the imposed displacements are simply empirical. Likewise, there are associated damage values that are not exact values. Since there is no reference value for this type of modeling, we check on this test case only the non-regression of the code.
