Biotribology and biomechanics are evolving fields that draw from many disciplines. A natural relationship particularly exists between tribology and biology because many biological systems rely on tribophysics for adhesion, lubrication, and locomotion. This leads to many biomimetic inspirations and applications. The current study looks to mimic the function of articular cartilage in purely mechanical systems. To accomplish this goal, a novel coupling of phenomena is utilized. A flexible, porous, viscoelastic material is paired with a hydrodynamic load to assess the feasibility and benefit of a biomimetic thrust bearing. This study presents the dynamic properties of the coupled system, as determined from transient to steady operating states. The results indicate that bio-inspired bearings may have application in certain tribological systems, including biomechanical joint replacements, dampers, flexible rotordynamic bearings, and seals.
