Computational Structural Dynamics
Computational structural and solid dynamics (CSD) is one of the classical core disciplines within the fast-growing field of computational mechanics. Apart from the modeling of nonlinear geometrical and material phenomena in solid and structural mechanics itself, CSD also lays the foundation for computational contact dynamics and many coupled / multiphysics problems, e.g. fluid-structure interaction.
Our research activities in computational structural and solid dynamics cover a wide range of methods, from nonlinear solid (hybrid FE meshes, isogeometric analysis) and structural models (beams, shells) and corresponding finite element technology (EAS, ANS, F-Bar) to material modeling (hyperelasticity, viscoelasticity, elastoplasticity) at finite strains. Another focus are complex material phenomena such as anisotropy, fiber components, damage, fracture and multiscale modeling of heterogeneous materials.
A further interesting and demanding branch of computational structural dynamics is the modelling of highly slender continua. In countless applications, mechanical system performance is significantly determined by slender, rod-like components such as the fibers in industrial webbings or fiber-reinforced composite materials. In this context, our research work deals with the development of geometrically exact beam formulations, beam-to-beam contact algorithms and methods that model potential-based beam-to-beam interaction.
Computational structural and solid dynamics play an important role for almost all fields of application that are addressed by our current research project, such as:
