4. Nonlinear possibilities#

All 2D_ DIS_ * models can be used with STAT_NON_LINE and DYNA_NON_LINE. In this case, you must define a material with DEFI_MATERIAU.

4.1. Law of behavior#

The laws of behavior specific to these models, usable under COMPORTEMENT in STAT_NON_LINE and DYNA_NON_LINE the following ones (Cf. [U4.51.11]):

/ “ DIS_GOUJ2E_ELAS “

Modeling supported: All

/ “ DIS_GOUJ2E_PLAS “

Modeling supported: All

/ “ ELAS “

Supported models: All

In addition to the assignment of characteristics (AFFE_CARA_ELEM) the use of models DIS_T and DIS_TR with STAT_NON_LINE/DYNA_NON_LINE involves defining material characteristics (AFFE_MATERIAU).

4.2. Deformations#

The available deformations, used in behavioral relationships under the keyword DEFORMATION for operators STAT_NON_LINE and DYNA_NON_LINE are (Cf. [U4.51.11]):

/ “ PETIT “

The deformations used for the behavioral relationship are the linearized deformations calculated on the initial geometry.

Modeling supported: All

/ “ PETIT_REAC “

The deformations used in the incremental behavior relationship are the linearized deformations calculated on the updated geometry.

Modeling supported: All
