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

The properties of the material from which the plate is made are as follows:

Unidirectional (:math:`U`):

.. csv-table::

    ":math:`{E}_{l}=4.{10}^{10}\mathrm{Pa}` "," :math:`{E}_{t}=0.16{10}^{10}\mathrm{Pa}` ", "(:math:`l\iff x`; :math:`t\iff y`)"
    ":math:`{G}_{\text{lt}}={G}_{\text{lz}}=8.{10}^{8}\mathrm{Pa}` "," :math:`{G}_{\mathrm{tz}}=3.2{10}^{8}\mathrm{Pa}` ", ""
    ":math:`{\nu }_{\text{lt}}=0.25` ", "", ""


Stacking:

.. csv-table::

    "* Orientation:", ":math:`[0/90/0]`"
    "* Nature:", ":math:`[U/U/U]`"
    "* Thickness:", ":math:`[h/3/h/3/h/3]`"



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


* The plate is simply pressed on its outline


* Uniformly distributed pressure: :math:`p=3000\mathrm{Pa}`


Initial conditions
