Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]
, 2014 Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

Hydrodynamic modelling of hydrostatic magnesium extrusion [PDF]
, 2006 Wilson’s hydrodynamic model of the hydrostatic extrusion process is extended to meet the geometry found on residual billets. The transition from inlet\ud to work zone of the process is not considered sharp as in the model of Wilson but as a rounded edge,

Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
, 2013 The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).

Closing the Gap between the Workshop and Numerical Simulations in Sheet Metal Forming [PDF]
, 1996 The accuracy and reliability of numerical simulations of sheet metal forming processes do not yet satisfy the industrial requirements. In this paper we pay attention to the strategies which can be followed to decrease the gap between the real deepdrawing
