Damage in Sheet Metal Bending of Lightweight Profiles
| Funding: | German Research Foundation (DFG) |
| Project: | SFB/TRR188 • Subproject A05 |
| Contact: | Dr.-Ing. Rickmer Meya |
Bent parts made of high-strength steels are often produced by conventional bending processes such as air or die bending.
Granular Media-Based Tube Press Hardening
| Funding | German Research Foundation (DFG) |
| Project | TE 508/52-1 • SP 714/12-1 • BO 4174/2- |
| Contact | Eike Hoffmann M. Sc. • Sigrid Hess M. Sc. |
| Status | Completed |
The process combination of press hardening and tube hydroforming enables the production of high-strength hollow profiles exhibiting high stiffness.
Kinematic Profile Bending with Partial Cross-Sectional Heating
| Funding: | Deutsche Forschungsgemeinschaft (DFG) |
| Project: | TE 508/74-1 |
| Contact: | Eike Hoffmann M. Sc. |
In this project, the suitability of tailoring the mechanical properties and the reduction of geometrical deviations through partially heat-treating profiles in bending processes is examined.
Method for Producing Bent Profiles with Small Bending Radii and Closed Contours
| Funding: | BMWi/ZIM-ZF |
| Project: | ZF4101104US6 |
| Contact: | Johannes Gebhard M. Sc. |

Bending of CNC-stamped sheets into profiles is a flexible and economical possibility for the production of frame structures.
Evaluation of Global and Local Ductility of AHSS and Stainless Steels
| Funding: | ReCIMP |
| Contact: | Dr.-Ing. Christian Löbbe |
The ability of a metal to withstand uniformly distributed strains is termed as global formability and, conversely, the ability to resist fracture under highly localized strains defines its local formability (see Figure a).
Shear Cutting and Hardening of Gears in Multi-Stage Tools
| Funding: | ReCIMP |
| Contact: | Dr.-Ing. Christian Löbbe |
In automotive engineering there is a conflict between the lightweight design and the maintenance of crash safety.
