Fig. 2: Validation of numerical simulations by experiments (here, film thickness measurements) in rolling, sliding and spinning lubricated contacts. Left: FEM solution on the left, interferometric picture on the right for a ball-on-disk contact; U0 = 2 m/s, W=400 N. Right: FEM solution (top) and interferogram (bottom) for a torus-on-plane contact; U0 = 3 m/s, W=400 N.
