Research professorship for Prof Peter Starke

Universities of Applied Sciences (UAS) are valued for the practical training they offer their students. What is less publicised is that successful research is also carried out there. In addition to teaching, many professors are also involved in research - often in cooperation with external partners from industry and society, as the application focus also plays a major role in research at UASs.

In order to give lecturers with a strong research background more freedom for science, the University of Applied Sciences Kaiserslautern has now awarded eight so-called "specialisation professorships". The holders of the new professorship format can devote themselves more intensively to their research over a good five years. During this time, their teaching commitments will be reduced and balanced out by teaching staff.

The following academics have been awarded the eight specialisation professorships: Prof. Priv.-Doz. Dr.-Ing. habil. Peter Starke, Prof. Dr.-Ing Sven Urschel and Prof. Dr.-Ing Christian Schumann (Department of Applied Engineering Sciences); Prof. Dr. rer. nat. Bernd Bufe, Prof. Dr. phil. Alexey Tarasov and Prof. Dr Dieter Wallach (Department of Computer Science and Microsystems Engineering); Prof. Dr Marion Rauch and Prof. Nora Mertes (Department of Building and Design).

Fabian Weber is the new chief engineer at WWHK

Fabian Weber has taken over the position of senior engineer at the WWHK as of 15 August 2023. At the same time, he will head the "Fatigue and Fatigue Life Calculation" working group and is thus responsible for 4 ongoing projects currently funded by the DFG and the BMUV.

We are delighted about this positive and profitable collaboration and are looking forward to future research activities.  

New DFG project brings personnel reinforcement to WWHK

In cooperation with the WPT of the TU Dortmund University, the new DFG project "Quantified evaluation of the influence of stress frequency on the fatigue behavior of unalloyed steels for implementation in resource-efficient service life prediction methods" has been processed since July 2023 with a project duration of 24 months. Jonas Ziman, who has been employed at the WWHK since successfully completing his master's degree at Saarland University, is responsible for the project.

High-tech analytics from the German Research Foundation (DFG)

The University of Applied Sciences Kaiserslautern has successfully applied for a large-scale equipment campaign of the German Research Foundation (DFG). The approved funds will be used to purchase a high-resolution scanning electron microscope (SEM), which will provide a variety of new possibilities for knowledge-oriented research at the university. The lead applicant and project coordinator for the University of Applied Sciences Kaiserslautern is Prof. Peter Starke.

New cooperation between WWHK and Evident

Industrial cooperation is immensely important for our research at the WWHK.

The results will be used in the simulation activities of the working group Electrotechnical Systems of Mechatronics to develop components with specific magnetic properties for the cell containers. The research project and the procurement of the Kerr microscope is financed by the Carl-Zeiss-Foundation.

 

New research project at WWHK

On October 1, 2020, the WWHK started the second phase of the joint project as a new project partner: Microstructure-based service life calculation "MibaLeb II".

The joint project is concerned with the development of a method for assessing the remaining service life of metallic nuclear power plant components that have aged during operation.

The second phase of the joint project, which is funded by the BMWi, involves transferring the results, findings and methods previously determined in the first phase of the project to real and actually loaded materials and components used in nuclear power engineering. The WWHK aims at the determination of individual aging conditions that correspond to real damage conditions. Thus, concrete statements can be made regarding the integrity and the remaining lifetime of nuclear power plants.

The further development of the StrainLife method with regard to a multi-parameter approach, in particular to better describe the transition from the LCF to the HCF range, is also a further research focus of this joint project.

Partners in the joint project are TU Dortmund University, Saarland University, MPA University Stuttgart and the Society for Plant and Reactor Safety.

Further information about the joint project can be found here
