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

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

We use C_ PLAN modeling. The main constraints ratio :math:`{\sigma }_{2}\mathrm{/}{\sigma }_{1}` is set to :math:`0.52`.


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

The mesh contains 1 element of type QUAD4.


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

We test the deformations and stresses at node :math:`N1` in Figure.

notes
---------

The first two measurement points allow you to compare the slope at the origin of the Stress-Deformation curve. The last point corresponds to the breaking stress.
