Asperity level conformity in partial EHL part1:its characterization
Traditionally in partial elastohydrodynamic lubrication (EHL)the contact through lubricating films has been modeled assuming random contarct and taking into accountratio of film thickness to r.m.s roughness(h/o).In some ...
A systematic methodology to characterise the running-in and steady-state wear processes
An improved methodology has been developed to characterise running-in and steady-state wear processes. The experimental study was conducted with En 31 steel specimens on reciprocating tester with ball-on-flat geometry under ...
Acoustic emission in dynamic compression and its relevance to tribology
In the present work an acoustic emission (AE) technique is used to detec: the initiation and propagation of short cracks in compressive cyclic loading. A mild steel surface was subjected to cyclic compressive stress of 100 ...
Response of dynamically stressed material in sliding
Sliding wear has been modelled on the basis of adhesive transfer as well as fatigue. In fatigue wear modelling it is assumed that the repetitive normal and tangential stressing is responsible for crack growth leading to ...
Asperity level conformity in partial EHL. Part II - Its influence in lubrication
Surface was confermity characterized in an eariler study(27)on the basis of composite roughness profile.In this paper the influance of surface conformity in luberication is reported.The resuls of experiments under high ...
Assessment of engine liner wear from bearing area curves
This paper proposes a new procedure to evaluate engine liner wear volume and wear depth particularly for short duration engine tests.The method is based on the fact that honing depth is not removed when small amount of ...
