I am trying to bond these four surfaces together so that they act as one body.  This is a simplified example for a much larger assy that I am working on and I want to verify results first.   I need the larger assy to have components bonded together via mating faces rather than just edges.

Hand calc from the results indicates that they are acting like a leaf spring- not bonded.  My Contact Set is between faces of the surfaces (not the edges).  I've tried all sorts of combos.  Global bonding via Component Contact, manual bonding via Contact Set, non-touching faces option selected,  etc.

How do I bond faces together so that they act as one?
