Hi,
I have a methodological question. I try to create the facet joint contact of two vertebrae in radioss. I have the bone model as stl file imported, and know that a very small cartilage layer (0.2mm) coats the surface of the bone at the location of contact on both sides. Friction is negligible.
--> see images: , ! (red and yellow surface are the cartilage layers)
My idea was to create a shell layer with 0.2mm offset from the surface and connect it to the solid bone using a type 2 contact with elastic behaviour (penalty formulation). I do this on bodes sides and define a type 7 contact between the two shell layers. Is this the correct approach? What parameter (especially for the type 7 contact) are important and how to set them correctly?
Thanks in advance!
