ALCAN Experience with HyperXtrude 9.0 and 10.0
Mehdi Ben Tahar, Alcan
Rio Tinto Alcan extrudes aluminium alloys for a wide range
of applications such as building, automotive, rail and aerospace.
For both profiles with large volume production and for niche
products with specific technical requirements Alcan is continuously
looking for competitive advantage. Extrusion modelling by
using FEM code is an efficient way to reach this objective.
Alcan has used the Altair product HyperXtrude for several
years to support plants developing more reliable die designs,
increasing productivity and assessing profile quality issues.
The main challenges for numerical simulation today are the
reduction in response time for die design on the one hand
and the improvement in model predictions on the other hand.
In this context, we will discuss in this presentation: the
advantage in switching from Hexa elements (HX 8.0) to tetra
elements (HX 10.0); the time saving and flexibility offered
by the wizard tool; feedback on transverse weld calculations
and a new tuning parameter; and the use of the export tool
to mesh temperature and loads on the work piece contact surface
for die calculations.
