# Conformability elastic material compressed on a wavy surface

Hey there,

I'm struggling in finding the useful equations to determine some conformability parameters for a finite elastic material (EPDM) compressed on a rigid slightly wavy surface. I would like to optimize the thickness of the elastic material in terms of indentation depth and thus contact area and pressure. To describe the situation I've added the following picture.

I would like to determine indentation depth u in terms of thickness t, pressure P and elastic modulus E. Could you assist me in finding the solution.
