Based on the micro-continuum Stokes [1] theory, this paper investigates theoretically the rheological effects of couple stressfluids on the lubrication performances of flexible finite porous journal bearings. A modified Reynolds equation is derived in the fluid film. The flow in the porous elastic bearing is described by Darcy's law. These equations are discretized by finite differences method, coupled using a sequential algorithm and solved iteratively by Gauss-Seidel over-relaxation method. The numerical results of the present simulations show that all these effects have a significant influence on journal bearings performances.
