| Abstract: | In this paer, by the use of the method of characteristic line of stress wave, a prediction analysis for the sacond impact of an elastic bar impacting on a rigid block is given. It is shown that for a certain ratio of the mass of the bar to that of the block, the second impact will be happened after the first impact. |
