Abstract: In a refined analytical model for the hydrodynamic lubrication of cold extrusion, effects of viscous heating in the inlet zone and surface temperature in the work zone are included to estimate ...

Abstract: The thermal hydrodynamic lubrication theory is extended to hydrostatic extrusion of a strain hardening metal. The effects of viscous heating in both inlet and work zones, and surface temperature ...

Abstract: An analysis of the lubricant flow in zones of plastic deformation is developed. This includes the effects of different surface temperatures and shear heating within the lubricant film. Thermal ...

Abstract: An analytical model for the isoviscous hydrodynamic lubrication of deep drawing is developed. The model covers the complete drawing stages from sheet metal blank to the drawn cup-shaped product. ...

Abstract: An analytical model for the hydrodynamic lubrication of hydrostatic extrusion is developed. This includes the effect of viscous heating on the film formation process and the effect of viscous ...

Abstract: An equation which is equivalent to the steady, one-dimensional incompressible Reynolds equation but which takes account of viscosity variations across the lubricant film thickness due to energy ...
