From time to time, I calculate 2d and 3d mechanical minimizing compliance problems. This is some kind of leasure while I work on the piezo optimization - so don't take it serious, it's just for fun. On the other side, some optimizations don't really fit to what I expected from publications. So if you also do also thus optimizations, please let me know if you have the same or different results. I can give the parametrization details on request. I use quite fine discretizations and a filter regularization as given in [2] to make the images nicer .:)
The cantilever is in my opinion too thin on the right end which is loaded.
This bridge gets its load from the top. I miss a lower horizontal bar.
Here the bridge has a lower load in the center.
This is a aqueduct, it looks much cooler in 3d. Thanks to Tom for the suggestion for this optimization problem.
If you have any ideas what could interesting to optimize, just let me know.
