COFs normalized by the highest COF in case of FEM and semi-analytical prediction, (a) 40-term Generalized Maxwell model fitted to the storage modulus, countersurfaces A: 𝜇^Force_max=0.044, 𝜇⁰_max=1.1𝐸−3. (b) 40-term Generalized Maxwell model fitted to the storage modulus, countersurfaces B: 𝜇^Force_max=0.062, 𝜇⁰_max=3.5𝐸−3. (c) 40-term Generalized Maxwell model fitted to the loss factor, countersurfaces A: 𝜇^Force_max=0.054, 𝜇⁰_max=2.9𝐸−3. (d) 40-term Generalized Maxwell model fitted to the loss factor, countersurfaces B: 𝜇^Force_max=0.085, 𝜇⁰_max=1.6𝐸−2.
