In this paper, the relation between the impact load history and the impacted point on a cantilever beam is theoretically investigated and the results are verified by the experiments. In the theoretical analysis the impact load history is obtained by the use of the classical beam theory and Hertz's law of contact under the condition that steel bars or balls strike a semi-infinite beam in the vicinity of the free end. In the experiment the impact load history is measured by the use of a piezoelectric trans-ducer mounted on the cantilever beam, or by a strain gauge cemented on the bar. As a result, it is shown that the impact load history is much affected by the distance from the free end to the impacted point, and the theoretical results are in good agreement with the experimental results.
