Abstract

A simple model of two parallel plates with reference to human articular joints was suggested and studied in the presence of synovial fluid, Variation of pressure, load capacity, time of approach, concentration of lubricant, minimum film thickness and the effect of cartilage porosity upon lubrication, have been investigated. The mathematical analysis was based on the continuity of pressure and velocities at the interface of the synovial fluid film and the three car ilage layers possessing different porosities. The study brings out many valuable and important results which are in good agreement with earlier experimental observations.
