The coefficient of restitution is mostly required for impact analysis in multibody dynamics. Using a multiscale simulation approach the coefficient can be computed on a fast time scale. Thereby modal models with local contact models proof to be efficient and accurate models for the simulations on the fast time scale. For many impact systems the coefficient of restitution is assumed to be deterministic, depending on essential parameters such as material, shape and initial collision velocity. In this paper impacts on beams are investigated numerically and experimentally. The investigated beam impacts feature multiple impacts, resulting in an uncertainty for the coefficient of restitution.
