RUB » Departments » Chair of Continuum Mechanics

The group of Daniel Balzani is active in developing methods for the continuum mechanical modeling and simulation of complex materials. Focus is on the development of scale-coupling numerical methods as well as new material models which enable the simulation of materials such as multiphase steels, textile membranes, soft biological tissues, fiber-concrete composites, or hardmetal composites by incorporating uncertainties at different scales. Increasingly, the experimental characterization of nonlinear material properties as well as the unique identification of material parameters become more important.

Chair of Continuum Mechanics Presents at the 9th GACM Colloquium on Computational Mechanics

28.09.2022: The 9th annual colloquium on continuum mechanics organised by the German Association for Computational Mechanics (GACM) took place from the 21st to 23rd of September. This event was jointly hosted by the Institute of Structural Analysis and the Institute of Mechanics at the University of Duisburg-Essen. Dennis Ogiermann, Sharan Nurani Ramesh and Johannes Riesselmann presented their current work in the fields of biomechanics and gradient-enhanced mixed finite element methods.

Chair of Continuum Mechanics at the Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM'22, Aachen)

01.09.2022: 92nd Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM'22), which took place in Aachen from August 15 to 19, 2022, has successfully come to an end. The Chair of Continuum Mechanics presented a whole range of current research work, from biomechanics to higher-order models for microelectromechanical structures. The lecture program can be found under the following link. A total of 13 presentations were given: Experienced scientists and fresh doctoral students presented new scientific developments of the Chair. This was the first opportunity in the last two years to meet in the presence the entire "mechanical" community in Germany resulting in lively discussions about current scientific questions and potential cooperation. See you next year at the GAMM annual meeting in Dresden!

Presentations at the WCCM 2022

05.08.2022: This year's "15th World Congress on Computational Mechanis (WCCM)" (initially planned to take place in Yokohama) was held in online format again. Here, during the time period from 31. July to 05. August, Niklas Miska, Mehran Motevalli, Dennis Ogiermann, Johannes Riesselmann, Klemens Uhlmann and Dennis Wingender used the opportunity to present their current research results and get into the exchange of scientific ideas on the international stage.

Presentation at the ECCOMAS 2022

26.07.2022: Maximilian Köhler gave a talk in Oslo at the ECCOMAS with the title "Multidimensional Rank-One Convexification of Incremental Damage Formulations: Algorithmic Treatment, Implementation Aspects, and Numerical Analysis". The presentation was created in collaboration with the mathematics cooperation partners from Augsburg Timo Neumeier, Daniel Peterseim and Malte A. Peter.

Within the talk it was shown how to construct multi dimensional rank-one convex envelopes and which properties they have within the application of continuum damage mechanics.

SPP 2256 Winter School in Augsburg

26.07.2022: Prof. Balzani presented at the winter school "Multiple Scales in Mathematics and Engineering" in Augsburg a lecture series with the title "Computational Homogenization - Introduction to the FE2-Method". The lecture series started with basic concepts of the method. In the second part of the presentation recent research results were presented as e.g., extension to dynamic problems and dual phase steel application.

International Symposium in honor of Professor Gerhard A. Holzapfel’s 60th birthday

26.07.2022: Biomechanics:
Challenges of the Next Decade, Graz, June 30 – July 1, 2022
Prof. Dr.-Ing. Daniel Balzani gives talk about Mesh-independent simulation of damage in soft biological tissues

Objectives of the symposium

Biomechanics is a challenging subject that studies living systems by means of the development, extension, and application of mechanics to better understand biological, engineering and medical phenomena. Nonlinear continuum mechanics, multiscale modeling, advanced 3D imaging techniques together with unprecedented predictive computational power allow us to solve cutting-edge biomechanics problems with rather complex patient-specific anatomies.
Interdisciplinary approaches that address phenomena at the nano-, micro-, or macro-levels are often required to solve such problems. Mechanics, natural sciences such as biophysics, biochemistry, and mathematics, as well as biomedical-, tissue-, health care-, computer- and biomolecular engineering sciences need to be combined with medicine to tackle real-world problems.
This symposium aims to gather the expertise of established and emerging scientists with backgrounds in the relevant areas of solid (bio)mechanics. It will highlight the state-of-the-art research in mathematical modeling, computational simulation, and experimental methods for testing of a range of biological tissues. In addition, it will highlight some major challenges of the next decade and how we can be better prepared for them.

SPP 2311 Kickoff Meeting - Stuttgart

25.07.2022: The kickoff meeting for the Priority Program 2311 titled "Robust Coupling of Continuum-biomechanical In Silico Models to Establish Active Biological System Models for Later Use in Clinical Applications – Co-design of Modelling, Numerics and Usability" took place on the 23rd and 24th of May in Stuttgart. Sharan Nurani Ramesh, Klemens Uhlmann and Daniel Balzani presented the current developments in the research project "Modeling and simulation of pharmacomechanical fluid-structure interaction for improved cardiovascular disease treatment".
