Tension Only LINK180

Figure 1: Von Mises Stress Animation

LINK180 is a very interesting element which allows tension but not compression. A snippet in a Beam element does the trick of configuring beams in Workbench into tension only beams.

The example problem has a thin plate that has a Revolute joint in the middle that rotates \(\pm3^o\). The two chain LINK180 on each sides of the plate will thus take turns being in tension and be relaxed.

The forces plotted using SMISC1 shows forces in tension.
