Computational Biomechanical Modeling Of The Human Knee During Kneeling, Tariq R. Abo-Alhol
Computational Biomechanical Modeling Of The Human Knee During Kneeling, Tariq R. Abo-Alhol
Electronic Theses and Dissertations
Total knee replacement benefits patients who suffer from severe knee pain or joint stiffness and other joint related illnesses that limit everyday activities. There has been an increase in the number of procedures performed each year and a need to evaluate the performance of these implants during specialized activities such as kneeling. Most computational studies lack insight into inter-patient variability and the results do not apply to large population. This study developed: (1) three-dimensional explicit finite element (FE) models to investigate natural and implanted knee joint kinematics and bone strain and (2) a platform to enable population-based evaluation by combining …
Effect Of Rolling On Viscoelastic Fluids Using A Novel Testing Device, Aswini Mangadu
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 …
