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


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

We use a D_ PLAN modeling.


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

The mesh contains:


* 276 SEG2


* 3672 QUAD4


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

Normal contact and tangential frictional forces are tested.

Normal forces:

In addition, if we compare the curves obtained with those in the literature, we obtain the graph in the figure.
