8. F modeling

8.1. Characteristics of modeling

Modeling: AXIS (axi-symmetric).

Type VMIS_ISOT_TRAC elasto-plastic behavior law whose traction law is identical to that of B modeling.

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

8.2. Characteristics of the mesh

The mesh is identical to that of modeling A.
