Transient mixed lubrication model of the human knee implant

The human knee implant is computationally modelled in the mixed lubrication regime to investigate tribological performance of implant. This model includes complex geometry components, unlike elliptical contact models that approximate this geometry. Film thickness and pressure results are presented for an ISO gait cycle determine present within during its operation. It was found it possible span between elastohydrodynamic, boundary depending on operating conditions observed one condyle were not necessarily representative other. Multiple points same condyle, which cannot be computed by solvers. can used balance forces all directions, instead only normal loads, as often done models. work initial step towards understanding role characteristics when physiological conditions.
