Answer:
If a contact between two superimposed plates or solids is to be simulated, it is usually necessary to model a contact solid between the two plates / solids with a thickness from center axis to center axis of both contact surfaces.
The material of the contact solid should be the same as that of the two surfaces to be connected. If the materials of the surfaces are different, we recommend using the material with the poorer properties for the contact solid.
