N modeling
==============


Characteristics of modeling
------------------------

Modeling: 3D.

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

The thermal deformation field from the thermomechanical calculation is extracted in order to be used as a control variable EPSA (command AFFE_MATERIAU) to represent a state of initial deformations of the structure.


Characteristics of the mesh
----------------------------

The mesh is identical to that of modeling I.


Tested sizes and results
------------------------------

Only the point in the middle of the crack front shown is tested.
