| Abstract: | In this paper, it presents an investigation on the transverse impact of a semi-infinite elastic rod with initial velocity on a finite elastic beam resting on an elastic foundation. By the use of the Galerkin principle, the approximate formula of the impact force has been obtained. A discussion on the result whence to obtain the related conclusion is also given. |
