A hybrid sharp-diffuse interface approach to accurately model melt pool dynamics with rapid evaporation in laser-based processing of metals
Nils Much, Andreas Koch, Christoph Meier +1
Predictive simulation of melt pool dynamics in laser-based processing of metals, e.g., laser beam welding or laser powder bed fusion additive manufacturing, requires accurate resol…

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…

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…
