r5.03.22 Law of behavior in large rotations and small deformations

Summary:

The formulation adopted to treat large rotations and small deformations is described here. This formulation is valid for all the laws of behavior defined under COMPORTEMENT of the STAT_NON_LINE command and equipped with three-dimensional (3D), axisymmetric (AXIS) models, in plane deformations (D_ PLAN) and in plane constraints (C_) and in plane constraints (C_ PLAN) models.

This feature is chosen using the keyword DEFORMATION =” GROT_GDEP “under COMPORTEMENT.
