Abstract: The two-dimensional heat transfer between the strip and rolls in strip rolling is modeled by one-dimensional heat conduction equations adopting Lagrangian coordinate systems on the contact surfaces. ...

Abstract: This paper presents an upper bound approach to analyze axisymmetric extrusion processes. A cylindrical and a spherical coordinate system are defined to represent the die geometry and the velocity ...

Abstract: A simple analysis for the lubrication of saw-tooth surfaces with longitudinal lay under conditions of high fractional contact area is developed. This is then coupled with Wilson and Sheu’s ...

Abstract: Deformable coated materials hold promises for numerous new technologies. In this research, extrusion of polymer coated metal rods was investigated. Analytical models based on upper bound method ...
