Effect Of Rolling On Viscoelastic Fluids Using A Novel Testing Device, Aswini Mangadu

Dissertations and Theses

The purpose of this research thesis project was to develop a mechanical testing device that could enable us to load articular cartilage with a rolling/sliding motion. This novel device was then used to observe the effect of a rolling motion on the fluid film thickness of different lubricants (motor oil, synovial fluid and Hyaluronic Acid (HA)) to varying loads (1kg, 2,kg, 3kg and 4kg) and speeds (10, 25, 48 and 91 mm/s) applied on the sample fluids for 10 cycles. We were able to examine the effect of different speeds within each load for each of the fluid that was …
