Hello, I’m trying to simulate the bending of an optical fiber with initial tension to determine the additional stresses the fiber experiences during bending. The project is found here https://www.simscale.com/projects/aplank/fiber_bending/
To bend the fiber I applied a rotating motion the right end of the fiber and let it rotate for 90 degrees.
Regarding this project I have this question:
- When I ran the simulation with a simpler model the end of the fiber had a displacement of 15 mm when done bending. A small displacement is to be expected but this seems to be large considering I didn’t apply any stress. This seems to be caused by my choice of position of the rotating base point. I tried different base point positions but I could not find a solution for this large displacement. What would a good base point be?
The origin of the model is circled in the picture below.
