basic unknowns of the solid deformation subproblem are the displacements, and the corresponding discrete finite-element equations are derived by assuming that the surface traction t is given. Likewise, the basic unknowns of the lubrication subproblem are the pressure p and the void fraction λ, and the corresponding discrete finite-element equations are derived by assuming that the surface S, the film thickness h, and the average velocity u are given. The two sets of nonlinear equations are then solved simulta- neously using the Newton method. The tangent matrix needed in the Newton method is obtained by linearization of the finite- element equations, and here all the couplings discussed above are fully accounted for.
