A variationally consistent beam-to-beam point coupling formulation for geometrically exact beam theories
Ivo Steinbrecher, Nora Hagmeyer, Christoph Meier +1
Slender beam-like structures frequently occur in engineering applications and often interact at discrete locations through joints or connectors. Accurate modeling of such interacti…
Patient-specific coronary angioplasty simulations -- a mixed-dimensional finite element modeling approach
Janina C. Datz, Ivo Steinbrecher, Christoph Meier +6
Coronary angioplasty with stent implantation is the most frequently used interventional treatment for coronary artery disease. However, reocclusion within the stent, referred to as…
A fully coupled regularized mortar-type finite element approach for embedding one-dimensional fibers into three-dimensional fluid flow
Nora Hagmeyer, Matthias Mayr, Alexander Popp
The present article proposes a partitioned Dirichlet-Neumann algorithm, that allows to address unique challenges arising from a novel mixed-dimensional coupling of very slender fib…
A consistent mixed-dimensional coupling approach for 1D Cosserat beams and 2D surfaces in 3D space
Ivo Steinbrecher, Nora Hagmeyer, Christoph Meier +1
The present article proposes a novel computational method for coupling arbitrarily curved 1D fibers with a 2D surface as defined, e.g., by the 2D surfaces of a 3D solid body or by…
Fluid-beam interaction: Capturing the effect of embedded slender bodies on global fluid flow and vice versa
Nora Hagmeyer, Matthias Mayr, Ivo Steinbrecher +1
This work addresses research questions arising from the application of geometrically exact beam theory in the context of fluid-structure interaction (FSI). Geometrically exact beam…
A multi-scale FEM-BEM formulation for contact mechanics between rough surfaces
Jacopo Bonari, Maria R. Marulli, Nora Hagmeyer +3
A novel multi-scale finite element formulation for contact mechanics between nominally smooth but microscopically rough surfaces is herein proposed. The approach integrates the int…
