H modeling
==============


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

We use a 3D model_ HHO_121 with HEXA27 elements. The mesh used is an extrusion of the mesh from modeling :math:`A` over a height of :math:`\mathrm{0,1}m` with a single element in the thickness. All degrees of freedom are blocked according to :math:`Z` in order to get closer to the hypothesis of plane deformations used in the :math:`A` and :math:`B` models. The behavior is GDEF_LOG.


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

Number of meshes: 1731

QUAD9: 1052

HEXA27: 480


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

We test the :math:`\mathit{SIYY}` coordinate of the stress tensor at various points along the :math:`\mathit{IJ}` path. We test against modeling :math:`B` (AUTRE_ASTER).

In addition, we test (in non-regression):
