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. 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. [:external:ref:`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). Deformations ------------ The available deformations, used in behavioral relationships under the keyword DEFORMATION for operators STAT_NON_LINE and DYNA_NON_LINE are (Cf. [:external:ref:`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
