Umm, I don't think that's really what's going on here.  Quite often adhesives 
are strong in shear and tension but weak in peel (kinda like velcro).  The 
purpose of those little rivets is NOT to take the shear and/or tension loads, 
but just the peel forces.  This allows the adhesive to do the work in shear 
and tension, but not be subjected to peel.
