Have the different strength criteria been implemented yet?
I am using Karamba3D 2.0.0 210504 WIP for Rhino 7. I have tried to model a concrete shell with in plane loads, see attached file.
shellFailureCriteria.gh (72.7 KB)
I tried setting the shell material strength hypothesis to Rankine. However, the results I got still fit the von Mises criterion. I tried to do it both with and without OptiCroSec to see if that was causing issues, but it does not seem like that is the problem. Also, it seems that only the tensile strength is used regardless of the magnitude of the compressive strength. Is this correct?
Lastly, I have a question about using the OptiReinf component. If I understand it correctly, OptiCroSec does not consider reinforcement and will find a suitable shell thickness, such that the cross section satisfies the target utilization (without cracks?). But then what is the point in using reinforcement if the cross section has sufficient bearing capacity without?
