The effect of contaminant films on creep coefficient and coefficient of friction (IM-WRI-023)

There is some evidence to suggest that, while the coefficient of friction can vary over a wide range (0.1 to 0.4), variations of creep coefficient (4 to 6.2 MN) are not in the same proportion (1). Kalker (2) gives an analytical solution for the creep force - creepage relationship:...
