Abstract:
|
Using the HyperXtrude module based on the Arbitrary Lagrangian-Eulerian(ALE) finite element method,steady-state simulation on the extrusion process of the hollow aluminum profile was presented.The field distributions of velocity,temperature,strain rate and stress of metal flow were obtained,and they were basically consistent with the producing test.It confirms that this method may successfully predict the potential defects occurring in the actual extrusion process and provide the theoretical basis for process parameters selection and die design.
