Title: Generated force and deformation at a conical end of aluminum bar due to impact. Theory based on the stress wave propagation in the bar.
Abstract: A theoretical relation is formulated by which the impulsive force generated at a contact part can be estimated, when an aluminum bar whose end is a truncated cone collides axially, perpendicularly against a plane wall at a comparatively low speed. In the formulation, the effect of the stress wave propagation is taken account. By comparing experimental results in which aluminum bars whose ends are of a variety of shape of truncated cones, collided against a devised sensing plate, with calculated results, the effectiveness of the theoretical relation for estimating the impulsive force which varies complexly with the shape of the contact end, impact velocity and length of the bar is confirmed.
