6. Nonlinear possibilities#
The nonlinear behaviors for GRILLE models correspond to particular incremental behaviors in STAT_NON_LINE:
GRILLE_ISOT_LINE for isotropic work hardening plasticity,
GRILLE_ISOT_CINE for bi-linear kinematic work hardening plasticity,
GRILLE_PINTO_MEN for Pinto Menegotto’s behavior.
For nonlinear MEMBRANE modeling, we’ll use the GROT_GDEP behavior in STAT_NON_LINE.
