On November 15, 2018, the CRC/Transregio 188 invited to its first industrial colloquium in the Dortmund Congress Centre, Germany. Latest research results on the subject of "Damage controlled forming processes" were presented to more than 100 international participants in 12 lectures and an accompanying poster presentation. The focus was on the analysis and characterization of damage on different scales as well as the influence of damage evolution in sheet metal and bulk forming processes. The variety of application examples presented by the speakers from industry and renowned research institutes as well as the great response from the participants underlined the high relevance of the topic for manufacturing technology.

 

At the conference of Materials Science and Engineering in Darmstadt in September, the TRR 188 offers a symposium on the topic of "Damage in Metal Forming". Recent scientific developments in the field of damage mechanics guided design of metal forming processes, modeling of damage initiation and accumulation mechanisms during cold and hot forming as well as the characterization of microstructural damage mechanisms in 2D and 3D will be presented and discussed with representatives of the European materials community.

Symposium organizers are Prof. Tekkaya and Dr. Clausmeyer from the IUL of TU Dortmund University and Prof. Münstermann from the IEHK of RWTH Aachen University.

 

The principal investigator of the project A02 Noomane Ben Khalifa has been appointed Professor of Manufacturing Engineering at Leuphana University of Lüneburg and Helmholtz-Zentrum Geesthacht on May 1, 2018. He was previously chief engineer for research at the Institute of Forming Technology and Lightweight Components at TU Dortmund University and was very involved in the application phase for the TRR 188. His research focused on bulk forming. The TRR 188 wishes him all the best for the establishment of the newly founded chair.

 

The industrial advisory board accompanying the research work of the TRR 188 met in the guest house of RWTH Aachen University on November 22, 2017. The focus of this session was the presentation of the objectives and the basic concept of the TRR 188 as well as its subprojects.

 

The CRC/Transregio 188 first introduced itself to a larger international audience at the "International Conference on Technology of Plasticity, ICTP" in Cambridge, United Kingdom. As part of a poster stand, the basic idea of the TRR 188 and the first selected results were presented from 17 to 22 September 2017. Numerous expert discussions with conference participants led to stimulating discussions and feedback on the topic of forming-induced damage.

 

To promote young scientists, the first doctoral seminar took place at TU Dortmund University from June 28 to 29, 2017. On both days the doctoral students of the TRR 188 were offered topics as "Scientific Publishing”, “Introduction to Optimization", and "The Virtual Exchange Platform". The aim of these doctoral seminars is the communication of working methods, the use of software and measuring methods as well as specialist knowledge. The seminar ended with a social event in the evening, giving the participants the chance of getting to know each other during a barbecue.

 

As part of the 36th IDDRG Conference 2017 "Materials Modeling and Testing for Sheet Metal Forming" the TRR 188 offered a “Mini Symposium”.
Renowned scientists had registered to give a talk on the topic “Damage and fracture in sheet metal forming”. Chairmen were Prof. Tekkaya and Dr. Clausmeyer from the IUL of TU Dortmund University.

 

The kick-off meeting on the occasion of the start of the first funding period of the TRR 188 took place on March 17, 2017 at TU Dortmund University. It was organized by the Institute for Forming Technology and Lightweight Components, having the spokesmanship of the TRR 188. The meeting was intended to give TRR 188 members the chance to get to know each other and to present their projects. In addition, organizational bases and various agreements for the successful work of the collaborative research center were launched.

 

Our colleague Dr. Christoph Kirchlechner from the Max-Planck-Institut für Eisenforschung, Düsseldorf, was awarded the Heinz Maier-Leibnitz-Prize by the DFG and the BMBF on May 3, 2017. It is the most important award for young scientists in Germany.

Christoph Kirchlechner was honored for his outstanding investigations on the deformation and failure of materials in mesoscopic dimensions. The innovative method of micro-Laue diffraction, which he has helped to develop, will also be used within the work of the TRR 188. It provides the first "live" insights into the accumulation of displacements at grain and phase limits during deformation, which enable a direct correlation of the mechanical properties with the underlying defect structure.

 

The German Research Foundation (DFG) approved the establishment of the Collaborative Research Center "Damage-Controlled Forming Processes" in November 2016. The funding amounts to more than 8 million Euros for the first four years. This major project is jointly organized by TU Dortmund University (head institution) and the RWTH Aachen University. Spokesperson of the TRR 188 is Prof. Dr.-Ing. Dr.-Ing. E. h. A. Erman Tekkaya of the Institute of Forming Technology and Lightweight Components (IUL) at the Faculty of Mechanical Engineering of the TU Dortmund University. Further participating institutions are the Brandenburg University of Technology Cottbus-Senftenberg (BTU) and the Max- Planck-Institut für Eisenforschung GmbH in Düsseldorf.

The aim of the CRC/Transregios 188 is to investigate a fundamental understanding of the damage mechanisms and their effects on the product properties in order to be able to quantify the degree of damage of a component in the long term, to control it, and to be able to adjust it specifically along the process chain.
