**v6.03.306** SSNP306 - Validation of the buckling criterion by selective search for eigenvalues
=======================================================================================================

**Summary:**

This test allows the validation of the generalization of the buckling criterion (loss of uniqueness of the solution, presence of bifurcation) for models in mixed formulations. The new criterion, which can be written as a problem with sub-stress eigenvalues, is validated for modeling non-local damage GRAD_VARI. The smallest modes of formulation GRAD_VARI and those of local modeling are compared in the case of a homogeneous study.
