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 at the Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM'23, Dresden)
30.05.2023: 93nd Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM'23), which took place in Dresden from May 30 to June 2, 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. A total of 10 presentations were given: Experienced scientists and fresh doctoral students presented new scientific developments of the Chair. There were lively discussions about current scientific questions and potential cooperation. See you next year at the GAMM annual meeting in Magdeburg!

Advanced seminar "Micropolar Continua and beyond" at TU Berlin
29.03.2023: A talk on "Numerically stable mixed FE for higher-order electromechanical coupling in piezoelectric solids" was successfully given by Prince Henry Serrao (research assistant at the Chair of Continuum Mechanics) and Dr. Sergey Kozinov during the Advanced Seminar on "Micropolar Continua and beyond". This seminar was organised at TU Berlin at the Department of Mechanics, Chair of Continuum Mechanics and Materials Theory by Prof. Wolfgang H. Müller.
The black belt of science
03.02.2023: On January 23rd, Dennis Wingender defended his thesis "Efficient Simulation of Brittle and Ductile Crack Propagation at Finite Strains through Metallic Microstructures based on Voxel Data". The thesis was awarded the highest grade with distinction. This means that Dennis W., a great friend of judo, now officially has a black belt in science.
The following journal publications were produced during his PhD studies: Simulation of crack propagation through voxel-based, heterogeneous structures based on eigenerosion and finite cells, Simulation of crack propagation based on eigenerosion in brittle and ductile materials subject to finite strains
22nd GAMM Seminar on Microstructures
26.01.2023: Maximilian Köhler, a staff member at the Chair of Continuum Mechanics at Ruhr-University Bochum, participated in the 22nd GAMM Microstructure Seminar and presented his talk titled "Advances in relaxed continuum damage mechanics at finite strains: Adaptive convexification and strain softening". The seminar was held at the TU Vienna. In the talk, he presented the new Reconvexify approach, which was recently published in this paper.
