4.1. Post-Forming Tube Temperature
4.2. Post-Forming Tube Fibre Angle Change
5. Conclusions
- Fibre angles at the start and end of tube bending zones were unchanged for all four bending angles during forming, indicating the absence of fibre movements beyond tube bending zones;
- The predicted fibre angles were within the standard deviations of the measurements at both tube intrados and extrados for tubes formed to all four bending angles.
