... thicknesses. The contact of a coated elastic smooth cylinder pressed by a rigid flat surface is shown in Fig. 1 . Assuming that the contact is small compared to radius of curvature ensures that the mixed boundary conditions can be applied to the top surface, r = R . To satisfy the boundary...

... coefficients are found by satisfying Eqs. 4 , 5 , 6 except for the radial stress condition in Eq. 5 and the displacement condition in Eq. 6 , i.e., except for the mixed boundary conditions on the top surface 12 a 0 = − p 2 1 1 − α 2 , b 0 = p R 0 2 1 − α 2...
