Abstract:The arbitrary Lagrangian-Eulerian(ALE) adaptive remeshing technology and the HyperXtrude software of transient finite element simulations were used on analogue simulation of aluminium extrusion processing. The field distributions of strain rate, stress, temperature and velocity of metal flow were obtained. The results are basically consistent with the experiment, which indicates that this method may successfully predict the defects in the actual extrusion process.


Key words: transient finite element simulations; complicated aluminium profile; arbitrary Lagrangian-Eulerian(ALE) method; die trial
