The qualitative analyses for the core formation inherent in a Bingham solid have already been given by the previous investigations for hydrodynamic lubrication of a Bingham solid. However, they don't make clear the behavior of the solid exactly, because the analyses for finite bearings are not sufficient.In this paper, a method of the vector analysis based on the flow characteristics of a Bingham solid, is presented for a finite bearing and shear stress and velocity distribution in the film are obtained.Using this method, we deduced the equivalent Reynolds equation of a Bingham solid and also established the general theory on the core formation. Consequently it became clear that the core formation is determined by the shear stress distribution which depends on the pressure gradient, the film thickness and the velocity of the slider surface.
