I am new to ABAQUS and is working on seismic base isolator. And I have modeled an isolator with alternate layers of steel and of rubber. The rubber is modelled using Mooney- Rivlin model. But I don't know how to properly define the interaction between steel and rubber layers. Please help me with it.

Rubber layer is 200mm in diameter and 8mm thick. Steel layer is 200mm in diameter and 3mm thick. The rubber is sandwiched in between steel.

I have attached the picture of the model
