Consistent coupling of positions and rotations for embedding 1D Cosserat beams into 3D solid volumes

Ivo Steinbrecher, Alexander Popp, Christoph Meier

This article proposes a mortar type finite element formulation for consistently embedding curved, slender beams, i.e. 1D Cosserat continua, into 3D solid volumes. A consistent 1D-3…
