„Opportunities of Residual Stresses in Forming Technology “

Industry Colloquium on SPP2013 on 22.06.2022 at the Science Congress Center, Garching TUM Research Campus The DFG-funded Priority Programme 2013, SPP2013 for short, started in October 2017. The six-year project period of a total of 12 research projects was divided into three sections of two years each. Thirteen universities with a total of 24 institutes are involved. Prof. Dr.-Ing. Wolfram Volk from the Chair of Metal Forming and Casting at the Technical University of Munich has been the coordinator since the beginning.


Informative Lectures, Intense Discussions and an Interesting Expert Exhibition

Shortly before the end of the SPP 2013, the results of the 12 projects were presented, highlighted and discussed in an industry colloquium. Around 70 participants from industry and science expressed great interest in the informative lectures and a well-designed presentation of the individual research projects in the accompanying trade exhibition.

Short films, posters and exhibits provided the participants with information about the various projects during the breaks in the lectures. The scientists directly involved were available to answer questions about their work

Objective and Project Phases

Prof. Dr.-Ing. Wolfram Volk, Head of the Chair of Forming Technology and Foundry Engineering, was responsible for welcoming and introducing the event. Chair of Metal Forming and Casting. He descriptively explained the overall topic.  


The Research Objective of the SPP2013 is:

„Targeted use of forming-induced residual stresses in metallic components “

The programme is divided into three phases:


1.        Proof of sufficient stability of residual stresses induced in components by forming technology

2.       Quantification of the improved component quality produced with different manufacturing processes

          and validation of the simulation models

3.       Optimisation of processes, machines and tools based on the results of the previous phases to

          optimise the products


Aimed at the participants from the industry, Prof. Volk explained: "In contrast to common production strategies, where residual stresses are considered critical to quality, our focus is on the opportunities for the inherent controllability of components. Since 2017, research teams from all over Germany have been able to provide evidence of stability and controllability in production processes for sheet metal and massive forming. A great deal of work has been done on fundamental understanding, simulation and industry-related measurement.  Our industry colloquium offers you the opportunity for information and exchange about the promising possibilities of using residual stresses in forming technology."

At the end of his presentation, Prof. Volk expressed his hope that the research projects would be continued, and the results applied in a wide range of areas with interested partners from the industry after their completion.

"It would be desirable to transfer knowledge in 2023/2024 after the end of the project, to pass on the project results to industrial processes and components," says Prof Volk.

He sees opportunities here in the development of innovative production processes in cooperation between industry and universities. He also believes in improving the quality of industry-relevant components through targeted process adaptation. In addition, there are possibilities for cooperation in a publicly funded research project with support from the industry. Advice, services, and the provision of material resources would go hand in hand.

Exciting Lectures of Current Research

The audience followed the high-calibre presentations on the results and knowledge of the research with rapt attention.

1.       "Strategies for Targeted Residual Stress Design in Massive Forming"

           by Prof. Peter Groche, PtU, TU Darmstadt.


2.       "Opportunities of Residual Stresses in Forming Technology - Use of Residual Stresses in

           Sheet Metal Forming" by Prof. Erman A. Tekkaya (IUL, TU Dortmund)


3.       „Simulative Prediction and Evaluation of Residual Stresses" by Prof. Markus Kästner (TU Dresden)


4.       "Residual Stress Analyses on Formed Metal Components - Challenges and Solution Approaches"

           by Dr. Ing. Jens Gibmeier (Karlsruhe Institute of Technology)


Overall, the industry colloquium met with great interest from all those present in the industrial environment. There was an exciting exchange between research and industry, both in the discussions following the lectures and in the discussions during the exhibition. There were intensive discussions regarding the possibility of transferring knowledge from research to industry.

"In forming production, residual stresses are often regarded as negative. Either one tries to avoid them or reduce them by heat treatment. The industry colloquium showed that residual stresses in forming processes can be controlled and their positive effects can be used. This is an important impulse for forming technology of the future," was the résumé of Ines Gilch from the Chair of Metal Forming and Casting.


Dr. Jens Stahl from Hilti Entwicklungsgesellschaft mbH was enthusiastic: "Trend-setting! A broad overview of current, industry-relevant research results."
