CONCLUSIONS
1- It is easy to create a tube stamping finite element model on Hyperworks by
passing through user profiles between block and incremental radioss.
2- Hyperworks allows to simulate deformations dependent on self-contact .
3- The results from Hyperworks will be compared with the results on prototype.
