.. csv-table::

    "Coatings:", ":math:`{E}_{x}={E}_{y}=4.{10}^{10}\mathit{Pa}` "," :math:`{G}_{\mathit{xz}}={G}_{\mathit{yz}}=4.{10}^{9}\mathit{Pa}` "," "," :math:`{\nu }_{\mathrm{xz}}=0.3` "," :math:`{\rho }_{1}=2000\mathrm{kg}/{m}^{3}`"
    "Heart:", ":math:`{E}_{x}={E}_{y}=4.{10}^{7}\mathit{Pa}` "," :math:`{G}_{\mathit{xz}}={G}_{\mathit{yz}}=1.5\mathrm{.}{10}^{7}\mathit{Pa}` "," "," :math:`{\nu }_{\mathrm{xz}}=0.3` "," :math:`{\rho }_{2}=50\mathrm{kg}/{m}^{3}`"


Shear coefficient :math:`k`: :math:`1/k=110.8`.

The Poisson coefficients are the same: :math:`{\nu }_{\mathrm{xz}}={\nu }_{\mathrm{xy}}={\nu }_{\mathrm{yz}}`.


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

The beam simply rests on sides :math:`\mathrm{AB}` and :math:`\mathrm{CD}`.


Initial conditions
--------------------

Not applicable.
