Shape Prediction and Improvement for Expansion of Non-Round Tubes

Funding: ReCIMP
Contact: Dr.-Ing. Till Clausmeyer

Increasing requirements on the utilization of assembly space result in more complex tube cross sections of containers.

Model Integration for Process Simulation

Funding: German Research Foundation (DFG)
Project: SFB/TRR 188 • Subproject S01
Contact: Alexander Schowtjak M. Sc.

Aim of the SFB/TRR 188 is to understand and predict damage. The identification of different material and model parameters is necessary in order to analyze forming processes in terms of damage.

Novel In-Plane Torsion Specimen for the Characterization of Damage and Hardening

Funding: German Research Foundation (DFG)
Project: TE 508/65-1
Contact: Heinrich Traphöner M. Sc.

Equivalent strains much larger than 1.0 are obtained for ductile materials in the in-plane torsion test with circumferential groove.

Analysis of Strain-Path Dependent Damage and Microstructure Development for the Numerical Design of Sheet Bulk Metal Forming Processes

Funding: German Research Foundation (DFG)
Project: SFB/TR 73 • Subproject C4
Contact: Florian Gutknecht M. Sc.

For sheet-bulk metal forming processes the sheet thickness is adapted to the loading. In this context, thickening is a typical subprocess at the sheet edge (see figure a).
