Compute Slab Yield Lines

Grasshopper

Hi I was wondering if anyone in here has any good resources or guides on how to compute the yield lines for a slab defined by a closed polyline. Something like this :

So I know the first example follows the Medial Axis or the Straight Skeleton, but I don’t think the Yield Lines are the same in all cases. Thank you!

So I found these papers, and this website I think they give a good idea for the algorithm
