Bending a Beam into a Möbius Strip using an Alignment Element

The new alignment element available in ADINA 8.9 can be used in many interesting industrial applications involving translations and rotations of parts and assemblies.

We illustrate the use of this element with a training video based on Primer Problem 58 from ADINA 8.9.

In this problem, the beam shown in Figure 1 is first bent into a ring. Next, the free ends of the original beam are twisted to form the Möbius strip shown in Figure 2. This problem can be solved with the 900 nodes version.

The video for this example is presented in 4 sections so that it is easier for you to review certain parts if necessary.
