K modeling
==============

Validation of the joint :math:`\mathrm{3D}` :math:`\text{HYME}` HEXA20 with the law JOINT_MECA_FROT


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

3D modeling for the elastic element.

3D modeling_ JOINT_HYME for the joint element


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

Number of knots: 32 (including 8 knots with degrees of pressure freedom)

The elastic element is a HEXA20.

The joint element is a degenerate HEXA20 (knots combined).


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

To test the hydraulic part, a pressure :math:`{p}_{\mathit{fluide}}\mathrm{=}500\mathit{Pa}` is imposed on the nodes :math:`\mathrm{NS19}` and :math:`\mathrm{NS20}` and the same value is tested on the nodes :math:`\mathrm{NS17}` and :math:`\mathrm{NS18}`.

We only do non-regression tests, by mixing the loading modes. The same load is applied as in modeling E, but the load in the third direction is added.
