Modeling A
==============


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

2D axi-symmetric modeling

Boundary conditions are modelled by:

On the nodes (N01, N02, N05, N06), DY=0.

The mechanical calculation is carried out with the Von Mises elasto-plastic behavior law with linear isotropic work hardening (keyword 'RELATION = VMIS_ISOT_LINE'). Work hardening restoration is activated only on the M1 mesh (keyword POST_INCR = 'REST_ECRO').


Characteristics of the mesh

.. csv-table::

    "Number of knots:", "6"
    "Number of meshes and type:", "2 QUAD4"



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

We test the non-regression of the values of :math:`p` and :math:`{\sigma }_{\mathit{yy}}` at the nodes N01 and N06 for the moments 89s and 200s.
