   .. py:method:: set_mortar()

      
      Set the mortar contact.

      A mort contact is a segment-to-segment, penalty-based contact.

   .. py:method:: set_tiebreak()

      
      Set the contact allow for failure.

      A tieback is a special case of this. After failure, the contact
      usually becomes a normal one-way, two-way, or single surface version.

   .. py:method:: set_friction_coefficient(static=0, dynamic=0)

      
      Set the coefficient of friction.


      :Parameters:

          **static** : :class:`python:float`, :obj:`optional`
              Static coefficient of friction. The default is ``0``.
