... parts. The design modification to reduce the variation will be discussed in the following section. Finite element method 3D Dies The design and analysis of hollow section extrusion processes are very difficult since die geometry and the flow characteristics are highly complicated...

...M.P. Miles; L. Fourment; J.L. Chenot A finite‐element model for calculating the die temperature profile for a hot‐forging operation is presented. The workpiece is modelled as a thermo‐viscoplastic material, while the dies are considered undeformable. Heat transfer between the dies and the workpiece...
