v6.01.119 SSNA119 — Damage to a specimen notched in AXIS

Summary:

This test represents a calculation of damage to a notched specimen. It allows the validation of modeling GRAD_VARI and GVNO in axisymmetry, for modeling AXIS_GVNO/AXIS_GRAD_VARI, which makes it possible to perform damage calculations regularized by the damage gradient, taking into account degrees of freedom of movement and damage at the nodes.

For GVNO the resolution of the criterion is global, unlike the GRAD_VARI modeling, which performs a local resolution, Gauss points by Gauss points. We validate three laws of behavior ENDO_CARRE (which is currently the only law that can be used with GVNO modeling), ENDO_SCALAIRE and ENDO_FISS_EXP.

The various models and laws of damaging behavior are tested:

• Modeling A: Modeling GVNO with the law of behavior ENDO_CARRE

• B Modeling: Modeling GRAD_VARI with the law of behavior ENDO_SCALAIRE

• C Modeling: Modeling GRAD_VARI with the law of behavior ENDO_FISS_EXP
