ABSTRACT On the basis of the Barus experimental research, the viscosity of an incompressible lubricant grows exponentially with its pressure. Therefore, the squeeze film issues between parallel circular plates lubricated with a non‐Newtonian couple‐stress fluid are reexamined in the present study by considering the effects of viscosity‐pressure dependency. According to the results, the influences of viscosity‐pressure dependency raise the load capacity and lengthen the approaching time of the plates. Numerical results under different values of the viscosity parameter and the non‐Newtonian parameter are also provided in tables for engineering applications. Copyright © 2012 John Wiley & Sons, Ltd.
