APPLICATION OF THE DISTINCT ELEMENT METHOD TO THE ANALYSIS OF THE CONCRETE MEMBERS UNDER IMPACT

In this paper, the distinct element method is applied to the analysis of the behavior of a structure under impact. At first, this method is applied to the one-dimensional wave propagation problem by comparing w ith the experimental results and the theoretical results. The effectiv eness of this method is confirmed by including not only elastic behavi or but also the fracture of a structural member. Second, this method i s developed to two-dimensional problems to simulate the behavior of a simply supported beam under an impact load. Finally, it could be shown that this method is effective to simulate wide phenomena from elastic behavior to a fracture under impact.
