12. J modeling#
12.1. Characteristics of modeling#
Modeling: 3D.
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.
This calculation consists of a 3D modeling of the E model, which is axisymmetric.
12.2. Characteristics of the mesh#
The mesh is identical to that of modeling I.
12.3. Tested sizes and results#
Only the point in the middle of the crack front shown is tested.
