Abstract
The method of collision analysis between granular materials and a plate is investigated numerically and experimentally. The motions of granular materials and the plate are analyzed by using the discrete element method and the finite element method, respectively. The damping characteristics of the plate are given by the Rayleigh damping. The validity of the analysis method is examined by a comparison of the experimental results. In the experimental approach, the response of an aluminum thin plate was measured when some steel balls collided with it. The contact behavior of the plate is evaluated by the displacement response and the frequency response of the plate.
