4. B modeling

4.1. Characteristics of modeling

Modeling: D_ PLAN (plane deformations)

Law of elasto-plastic behavior of type VMIS_ISOT_LINE.

The pre-deformation introduced via the keyword PRE_EPSI in AFFE_CHAR_MECA is defined by an analytical function.

4.2. Characteristics of the mesh

The mesh is identical to that of modeling A.

4.3. Tested sizes and results
