Benchmark solution
=====================


Calculation method
------------------

We do not have an analytical solution but curves obtained by different teams of researchers published in [:ref:`1 <1>`], [:ref:`2 <2>`] and [:ref:`3 <3>`].


Reference quantities and results
------------------------

Normal contact and tangential frictional forces are tested.
