If you start with the 10 node mesh

This is what I would like to have. The idea is to introduce some random “cuts”
in the mesh, where I can apply some boundary conditions.
I thought the easiest way to achieve this would have been adding new duplicated
nodes on the side using AMR.
Yeah, if that's the effect you want, then a single refinement followed
by duplicating the non-corner internal boundary nodes is exactly what
you want to do.
Could I “break” the mesh, use AMR, and then stitch back the nodes together?
You could but it would be more of a pain. Just do one refinement and
then break it afterward. Or, actually, you could also use TRI6
instead of TRI3 and break the middle node between the two triangles.
