v6.02.125 SSNL125 - Traction of a fragile bar: gradient damage

Summary:

This test allows the verification of fragile damage laws with gradients ENDO_SCALAIRE (modeling A) and ENDO_FISS_EXP (modeling B) in a non-homogeneous one-dimensional situation. Because of its 1D nature, this problem admits an analytical solution that exhibits two regimes of boundary layers: one of finite length (existence of a free border between the damaged zone and the healthy zone) and the other of infinite length (it extends to the border of the part).
