Highly slender fiber- or rod-like components represent essential constituents of mechanical systems in countless fields of application. In this thesis, mechanical models for slender beams and their contact interaction are proposed on the basis of the Cosserat continuum theory. From these models, geometrically exact 3D finite element formulations are derived that allow for an accurate, robust and efficient numerical simulation of complex mechanical systems composed of highly slender fibers with arbitrary orientation.
