Within the scope of the research activities of the department of statics and dynamics, innovative methods for the assessment of load-bearing capacity and serviceability of structures are developed and applied to practical construction tasks. A special focus is placed on the closest possible interlocking of design and calculation. A further field of research is the efficient and realistic modelling of application-relevant materials in the building industry.
The assessment of the load-bearing behaviour is carried out with numerical methods where possible, and with a combination of experiments and simulation where necessary. For experimental research, the Department of Statics and Dynamics possesses state-of-the-art measuring and testing equipment. The aim of the research is to gain fundamental knowledge about the applicability of innovative and efficient calculation methods in the field of structural analysis as well as material modelling. In doing so, the aspect of applicability in construction practice is always taken into account.
In addition to topics relevant to construction practice, interdisciplinary research projects are also carried out with cooperation partners from the fields of mathematics and mechanics. Here, too, the topics are predominantly application-driven, with the aim of finding more efficient solutions to engineering problems.
In order to strengthen the reputation of the Department of Statics and Dynamics of the BTU Cottbus-Senftenberg, the research results are published in renowned international journals and presented to a broad professional audience at national and international conferences. In this context, the scientific staff is involved at an early stage within the framework of the promotion of young researchers.
The research activities of the Department of Statics and Dynamics are divided into the following main areas:
Basic research in the field of isogeometric analysis
- Basic idea: Use of a uniform geometry description for design and calculation, in this case Non-Uniform Rational B-spline Curves and Surfaces (NURBS).
- Advantage: closer integration between design and calculation as well as superior accuracy by using the exact geometry.
- Additionally higher efficiency due to smoother approach functions
- Research in the field of numerical integration for NURBS
Structural analysis with innovative isogeometric formulations
- Shell and beam formulations for isogeometric analysis
- Adapted concepts for the interpolation of rotations
