Welcome to the Institute of Mechanics The Institute
The field of activity of the Institute of Mechanics is the theoretical and computer-based mechanics. Thereby, aspects of material modeling and the further development of the Finite Element Method are the main focus. Prof. Dr.-Ing. Jörg Schröder and his employees offer teaching of engineering mechanics 1-3, continuum mechanics, theory of materials as well as the linear and non-linear finite element method. teaching
Several projects founded by the DFG enable a wide networking regarding the research: The project "Parallel simulations of arterial walls: continuum mechanical modelling and numerical solution using FETI domain decomposition" is elaborated in cooperation with the faculty of medicine and the chair of numerical mathematics. The project "Statistically similar representative microstructures in elasto-plasticity" is realized within the DFG research group "Analysis and computation of microstructure in finite plasticity" (FG797). Further projects are "Construction and analysis of anisotropic polyconvex energy functions" and "Freezing and thawing of saturated porus media". The institute has successfully applied phenomenological material models for the macroscopic description of dual-phase steels to different sheet metal forming problems. Beyond that the research in the field of functional materials like piezoelectrica and ferroelectrica (FG 1509) are current topics as well as the development of new mixed finite elements or improved least-squares finite element. research

Together with colleagues from mathematics at the University of Cologne, mathematics at the Freiberg University of Mining and Technology and mechanics at the Ruhr-University Bochum we met to give lectures and present posters. The seventh working group seminar was a great success with many fruitful discussions and an intensive exchange between the groups.
Curious about ice Summer School in Cape Town
What effects does climate change have on the ice masses in the marginal ice zone of the Antarctic and on which topics are currently being researched in the Antarctic? In order to answer these and other questions about the Antarctic and to give students from different countries the opportunity to better study the conditions in the Antarctic, an international Summer School was held at the UCT Cape Town from 22-28 January. Students and lecturers from the University of Duisburg-Essen were among the participants. The event was organized in cooperation between the University of Uppsala and the University of Cape Town.
The progress of climate change in the Arctic is widely reported in the media. Everybody knows the pictures of ice masses breaking and falling into the water at the North Pole, but what is the situation in the southern hemisphere? The Summer School in Cape Town gave 22 participants the opportunity to get to the bottom of these and other questions. The students had the opportunity to compare the differences in conditions between the Arctic and Antarctic. Over five days, insights were provided into important topics that are necessary to understand the marginal ice zone of the Antarctic. The Marginal Ice Zone is the transition between the open ocean and a closed ice cover. Topics included climate models, the interaction of ocean, ice, and atmosphere, large and small scale simulations of sea ice dynamics, sea ice growth, predictions of iron development and algae growth. The different thematic blocks made it clear that these cannot be considered in isolation from each other, as each thematic area has complex interactions with the others. After the theories of the different areas were presented in the morning, in the afternoon there was the opportunity to do research on small projects. A highlight was the hands-on in the polar laboratory of the University of Cape Town. The students measured temperature profiles and the elasticity modulus of the ice samples. The determined modulus of elasticity, which indicates the stiffness of a material, is necessary, among other things, to assess and simulate large ice fields in Antarctica. The Summer School builds on the existing cooperation between the participating universities, in the context of which researchers from the University of Duisburg-Essen have already participated twice in expeditions to the marginal ice zone of Antarctica. "We are pleased about the good cooperation with the University of Cape Town", said Professor of the Institute of Mechanics, Jörg Schröder. His colleague and head of the Institute of Materials Science Doru C. Lupascu added: "The Summer School offered students and lecturers the opportunity to intensively exchange views on Antarctic research across the continents".
AGYA Summer School in Hebron and Bethlehem
From 17 to 22 August 2019 Dr.-Ing. Lisa Scheunemann and Dr.-Ing. Alexander Schwarz were invited as lecturers at the AGYA Summer School in "Numerical Simulations" at the Palestine Polytechnic University in Hebron in the West Bank. The twelve courses consisting of lectures and programming exercises covered the basics of the Finite Element Method. The Summer School equips students from different disciplines such as Math, Physics, Chemistry, Environmental, Health and Aerospace Engineering with know-how on the topics of continuum mechanics, numerical methods for solids and fluids, iterative solvers and error estimates. The event is organized by the Arab-German Young Academy of Sciences and Humanities (AGYA) in cooperation with Palestine Polytechnic University (PPU), Bethlehem University (BU), and Palestine Academy for Science and Technology (PALAST).
Scientists on their way into the Antarctic ice - SCALE Winter Cruise 2019 A journey into the Antarctic sea ice
In July and August 2019, four scientists from University of Duisburg-Essen embarked on a three-week expedition to the Southern Ocean and the Marginal Ice Zone (MIZ) of Antarctica. Together with 100 scientists from 13 nations, they travelled on the South African research vessel S.A. Agulhas II to investigate the properties of sea ice in numerous experiments.
The scientists Dr.-Ing. Tommy Mielke, Felix Paul, B.Sc. from the Institute of Material Sciences, as well as Prof. Jörg Schröder and Dr.-Ing. Carina Nisters from the Institute of Mechanics were part of an interdisciplinary project funded by the SA National Antarctic Project (Southern Ocean Seasonal Experiment – SCALE) to investigate the conditions in the Antarctic region in particular during the winter months.
The Earth's polar regions are covered by sea ice, which is driven by atmospheric movements, wave movements and ocean currents and is subject to constant dynamics. Sea ice plays an important role in determining the polar climate and is believed to have a significant impact on the global climate. The forces within the agglomerate of the ice lead to the formation of pancake ice. The exploration of this region is an important task for many scientific and engineering disciplines.
The multidisciplinary research project of the Cruise was led by Professor Marcello Vichi, the director of the Department of Oceanography at University of Cape Town (UCT), and included 17 different research groups with different research interests in biology, chemistry and engineering. The Sea-Ice team led by Professor Sebastian Skatulla (UCT) was one of the research teams. The Sea-Ice group successfully took cores from both consolidated and pancake ice. These cores are used to determine the physical and mechanical properties of the ice. Strength tests, tests of thermal conductivity and salt content as well as hardness tests were carried out. In addition, samples of the so-called frazil ice were taken using equipment specially designed for this expedition. Frazil ice is a mixture of ocean salt water and the first crystalline structures of ice between the ice floes. In addition to salt content and temperature, viscosity was measured for this mixture. Electro engineers were also part of the Sea Ice team, who measured the movements of the ice floes using buoys. Another project was the observation of sea ice movements to define the limits of the MIZ.
Two women researchers and six male colleagues will receive this year’s Georg Forster Research Awards, granted by the Alexander von Humboldt Foundation. The award targets research personalities from transition and developing countries whose research to date has earned them international visibility whilst seeking to help solve development-related issues. The award winners are invited to spend time in Germany establishing and building collaborations with colleagues here. Valued at 60,000 EUR each, the research awards are financed by the Federal Ministry for Economic Cooperation and Development
One of the award winners, Paulo De Mattos Pimenta (60), will be a frequently scientific visitor at the Institute of Mechanics in the coming years. His first stay at the institute will be in March/April 2015. The Brazilian, who is actually a professor at the Universidade de São Paulo, is considered a pioneer of computational mechanics, working in strongly practice-related fields. He has developed methods of numerical analysis for numerous engineering projects in Brazil, including the construction of the Brasilia National Stadium for the 2014 World Cup. De Mattos Pimenta, who holds a professorship at the University of São Paulo, aims to strengthen long-term cooperation with the Institute of Mechanics at the University of Duisburg-Essen.
