7. E modeling

7.1. Characteristics of modeling

Modeling: AXIS (axi-symmetric).

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.

7.2. Characteristics of the mesh

The mesh is identical to that of modeling A.
