14. L modeling#
14.1. Characteristics of modeling#
Modeling: 3D.
Law of elasto-plastic behavior of type VMIS_ISOT_TRAC.
The pre-deformation introduced via the keyword PRE_EPSI from AFFE_CHAR_MECA is defined by a field ELGA derived from the thermomechanical calculation previously carried out.
This calculation consists of a 3D modeling of the H modeling, which is axisymmetric.
14.2. Characteristics of the mesh#
The mesh is identical to that of modeling I.
14.3. Tested sizes and results#
Only the point in the middle of the crack front shown is tested.
