Description
Summary:Squeeze film lubrication between two approaching surfaces is considered with reference to normally loaded human joints. The fluid between the surfaces is viscoelastic. The upper surface is a rigid rectangular plate and the lower surface is a porous rectangular plate composed of three thin layers with differing porosities. Analytical closed-form solutions are obtained for the pressure distribution and the load-carrying capacity. The effects of the viscoelastic behaviour of the synovial fluid and the effects of the porosity variation of the cartilage on the pressure and on the loadcarrying capacity are presented graphically.
