. For example, for the diametrical clearance of 100 m the minimum and maximum values of
the minimum film thicknesses in the hip simulator cycle for the two solutions vary by only 3.7% and 1.6%
for the Newtonian solutions, 4.5% and 0.8% for the non-Newtonian solutions. The film thickness contours
at two time steps (0.2 s and 0.64 s) occurring during the stance phase and swing phase respectively for the
hip simulator pattern are plotted in Fig. 6 (At 0.64 s the reversal rotation resulted in zero velocity). The film
thickness contours at 0.55 s and 1.1 s, occurring during the loading and swing phases respectively in the
physiological walking pattern are plotted in Fig. 7. The Newtonian and non-Newtonian film thickness
profiles on a cross-section at two different time steps (same as Fig. 6) in a walking cycle are compared in Fig.
8. The non-Newtonian viscosity contours at specific time steps are shown in Fig. 9, along with the minimum
viscosity through the two different gait cycles in Fig. 10.
