Abstract

To model the collision between two deformable structures, two typical examples (i.e. a free-free beam collides on to a cantilever beam and on to a simply supported beam) have been extensively studied. Some common features are revealed, for instance, the weaker beam always dissipates most of the input energy, no matter it is the striker or the target; most of the input energy is dissipated by stationary hinges rather than by the travelling ones; various local deformation models result in different local energy dissipation, but make very little influence in the global energy partitioning. It is also found that the elastic-plastic mode technique provides a valuable tool in predicting the global energy partitioning between colliding beams.
