The numerical simulation started from an initial steady-state solution as at the first time step in the walking
cycle, after three walking cycles the EHL solutions converged to a periodic solution. All the results
presented in this paper were obtained for periodic walking cycles. The magnitude of the minimum film
thickness and its location in the walking cycle were compared between the Newtonian and non-Newtonian
fluids, for a range of diametrical clearances between 50 m and 150 m. Results for the two loading
patterns considered, i.e., hip simulator and physiological conditions respectively, are shown in Fig. 4 (a) and
(b).
