Controlled impact of a finite elastic circular rod on an isotropic, elastic half‐space

Abstract

The wave propagation in an elastic circular rod following its impact on elastic half‐space is investigated until the instant of separation. The motion of the far end of the rod is assumed to be controlled during the whole process. An approximated response of the half‐space is used to calculate resulting deflections and stresses at the interface. These quantities are compared with the corresponding quantities due to the controlled impact on a rigid half‐space. It is seen that the flexibility of the half‐space has a moderating influence on both the displacements and stresses.
