A Weak Formulation of Constraints to Couple Rigid and Elastic Bodies - a Study with FEniCS
Many complex mechanical systems are simplified by considering them as multibody systems. In recent years, flexible multibody dynamics has become more and more in demand. In~\cite{simeon2013}, a weakly constrained joint model was presented, which in a well-defined way models the interconnection of an elastic and a rigid body by a massless rigid joint. However, the joint model assumes that the orien
