Torsional Deformation with a Cut

Before placing the rod in torsion, we glue two rubber rectangles near the interface on the outer surface of the tube. One is on the upside, another on the underside. These two rectangles will slip during animation. We observe that there is no deformation of the rectangular element when it is subjected to the torque.

Torsion causes the tube to slip longitudinally along the interface because it cannot resist shear along the cut.
