=====================


Geometry
---------

We consider a cube with side :math:`1m` placed on a rigid plane.

Material properties
----------------------

The material is isotropic elastic whose properties are:


* :math:`E\mathrm{=}209000\mathit{MPa}`


* :math:`\nu =0.3`


Boundary conditions and loads
-------------------------------------

On the upper face, a vertical displacement of :math:`\mathrm{-}\mathrm{0.1m}` is imposed. The rigid plane is embedded and a unilateral condition of contact is imposed between the cube and the rigid plane.
