Isothermal Hydrodynamic Lubrication in Hydrostatic Extrusion of a Work-Hardening Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a numerical method the film thickness and the pressure distribution in hydrostatic extrusion of a work-hardening material under hydrodynamic conditions are determined. A minimum or critical ...
Deep Drawing With Blank Holder Force Approximately Proportional to the Punch Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method of applying blank holding force approximately proportional to the punch force in cup drawing is presented. An annular urethane pad compressed between two parts of a punch expands ...
