| Abstract | A semianalytical model was proposed to study the vertical impact of a slender rod striking a rigid flat surface. Within the semianalytical model, we considered the longitudinal vibration of the rod by using continuum mechanics while employing a plastic contact model, an equivalent spring model, to describe the contact of the linear hardening hemispherical tip and a rigid flat surface. The predicted displacement and velocity histories along the rod agreed well with the corresponding finite element simulations. In addition, from the proposed semianalytical model, we determined that there was a critical length/diameter ratio that can be used for any plastic contact of a linear hardening rod. The critical length/diameter ratio was approximately 17 for a rod made of 316 stainless steel. Below this critical length/diameter ratio, the rod behaved as a rigid body, i.e., the velocities of different sections of the rod reversed simultaneously during the impact. Above this critical length/diameter ratio, the velocity of the top section reversed much earlier than the other sections of the rod; hence, the slenderness effect should be accounted for in these conditions. |
