Forming-Based Process Modeling of the Linear Winding Method

Funding: German Research Foundation (DFG)
Project: TE 508/56-1
Contact: Anna Komodromos M. Sc.
Status: Completed

Due to the increasing importance of electromobility the linear winding of noncircular coil bobbins (see figure a) has been analyzed in cooperation with the Institute of Production Science (KIT).

Development of a Model to Describe Springback and Residual Stresses Resulting from Bending at Elevated Temperatures

Funding: German Research Foundation (DFG)
Project: TE 508/59-1
Contact: Dr.-Ing. Christian Löbbe
Status: Completed

In order to model sheet metal bending at elevated temperatures, a process description was developed according to an experimental study.

Influence of the Cut Edge on the Formability of Steel

Funding: ReCIMP
Contact: Dr.-Ing. Christian Löbbe

The sensitivity of sheared Advanced High-Strength Steels (AHSS) to fail at the sheared edge is a critical problem for the automotive industry.

Development of a Technology for Bending U-Profiles

Funding: BMWi/ZIM-ZF
Project: ZF4101104US6
Contact: Johannes Gebhard M. Sc.

Bending of metal profiles is currently restricted to high bending radii and, therefore, bent products are limited to spacious constructions.

Damage in Sheet Metal Bending of Lightweight Profiles

Funding: German Research Foundation (DFG)
Project: SFB/TRR188 • Subproject A05
Contact: Dr.-Ing. Rickmer Meya

Profiles made of high-strength and ultra-high-strength steel materials are often produced by classic bending processes such as air and die bending.
