Currently, an artificial hip joint can be expected to last, on average, in excess of 15 years with failure due, in the majority of cases, to late aseptic loosening of the acetabular component. A realistic alternative to the problem of wear in conventional joints is the introduction of bearing surfaces that exhibit low wear and operate in the full fluid-film lubrication regime. Contact analyses ...

Abstract Lubricated contact processes are studied using classical molecular dynamics simulations for determining the entire range of Stribeck curve. Therefore, lateral movement two solid bodies at different gap height studied. In each simulation, a rigid asperity is moved constant above flat iron surface in lubricating fluid. Both methane and decane considered as lubricants. The three main lubr...

Tribological research is the study of lubrication, friction, and wear. Tribology of biomaterials is to study how the materials work and fail. This will help us to produce better biomaterials. Tribology plays a very important role in improving the design and making successful biomaterials for medical purposes. Joints of human body, such as hip, knee, jaw, dental parts etc., all need to consider ...

In this paper, the novel approach for the rotating machine as diagnosis method in detecting the faults during its operation was proposed based upon the infrared thermograph technique. As experimental works, by performing the test of operation at several lubrication conditions for the ball bearing applied in the rotating machine which there has been used broadly, diagnosis evaluation and fault a...

In the present investigation we have studied the peristaltic flow of a couple stress fluid in a non-uniform rectangular duct. The flow is investigated in a wave frame of reference moving with the velocity c away from the fixed frame. The peristaltic waves propagating on the horizontal side walls of a non-uniform rectangular duct is studied under lubrication approach. The exact solutions of velo...
