4. Nonlinear possibilities

4.1. Law of behavior

The law of behavior specific to this modeling, usable under COMPORTEMENT in STAT_NON_LINE and DYNA_NON_LINE, is the relationship ELAS_POUTRE_GR (Cf. [U4.51.11]).

4.2. Deformations

Only the “GROT_GDEP” deformation allowing the beams to be treated in large movements and in large rotations is available (Cf. [U4.51.11]). The deformations used in the behavioral relationship are the deformations of GREEN - LAGRANGE.
