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


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

We use a DST model (QUAD4).

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

The mesh contains 39 knots and 24 QUAD4 stitches.

notes
---------

Under the effect of the large displacements undergone by the structure, the QUAD4 cells become increasingly left during the calculation. The assumptions of modeling DKT are then no longer respected.
