Articular cartilage is a biological bearing in diarthrodial joints of vertebrate animals, it has remarkable lubrication performance that outperforms the current best manufactured bearing. However, debates on cartilage lubrication theories (weeping and boosted) are still fierce. This thesis focuses on the interactive effects between cartilage consolidation and lubrication by developing a coupled cartilage contact model. The contact interface (surface roughness and polymers) was modelled by a poroelastic system on top of a cartilage tissue. Results favoured the weeping lubrication theory.
