How to set boundary conditions for two parts that are in contact on one boundary but free to move?

Hi,
i have a problem with my boundary conditions. The attached file shows a simple overview. The blue part is material 1 and can be deformed. The orange part is material 2 and like a pellet that lies insind the blue part. The yellow circle shows the contact boundary. I tried:
1. contact pair, but the master and slave boundary are the same?
2. "roller", but physically not true, it can move to it's normal position. E.g. if the blue parts deforms, it builds with the orange part a V-notch. Think about it if you press down the upper right corner of the blue part.
3. it's no other contraint condition true
In words: this boundary is free to move to all dimentions, but the contact area can change. It could be the full length or just one point (depending on the deformed shape of the blue part)
Regards
