   Create a HingeRadauTwo beamIntegration object.
   Two-point Gauss-Radau integration over each hinge region places an integration
   point at the element ends and at 2/3 the hinge length inside the element. This approach
   represents linear curvature distributions exactly; however, the characteristic length for softening
   plastic hinges is not equal to the assumed plastic hinge length (equals 1/4 of the plastic hinge length).

   Arguments and examples see :ref:`HingeMidPoint-BeamIntegration`.
