My group has been trying to simulate the bending of a paper strip using Kangaroo. The paper strip has a slit in which we will slot the other end of the paper through to achieve the final form as shown.
We adapted scripts found on the forum and tried 3 methods; using (1) developable surface, (2) shell and (3) beam. We faced several issues and would like to seek your advice on which method to proceed with.
(1) Developable Surface
With this method, we can use the grab function to attempt bending the paper. However, we have little control in the bending and the mesh was not refined. We tried refining the mesh using C# script but after which, we were unable to bend the strip.
(2) Unstructured mesh as Shell
With this method, we can bend the strip (though not to the extent of bending into the slit). However, it takes a long time for the simulation to complete.
(3) Beam 6DOF
We believe this method can be easily implemented but are unsure about how we can introduce a slit into the beam.
We hope to get your advice on which method to proceed with. Thank you!
