All dimensions are in millimeters.


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

Young's module :math:`E\mathrm{=}200000\mathit{MPa}`

Poisson's Ratio :math:`\nu \mathrm{=}0.3`


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

Boundary conditions:

 Point :math:`{P}_{1}`: :math:`\Delta X\mathrm{=}\Delta Y\mathrm{=}0`

 Point :math:`{P}_{2}`: :math:`\Delta Y=0`

Charging:

 Strength: :math:`P\mathrm{=}1000N`

The load ratio is set to zero. The force value :math:`P` given above is therefore the maximum value of the fatigue cycle.
