The dynamic behaviors of a finite length bar with a continuously variable cross section colliding with a rigid wall are studied theoretically and experimentally. The impact end stress and the propagation of elastic waves along the bar are predicted under the assumption that the bar is thin, has small changes of its cross section. The analytical solution is obtained by the application of the Laplace transform. Numerical calculations are carried out for the case of truncated cones. The time variation of stress at the impact end and elastic waves along the cones are presented and compared with the corresponding experiments. The experiments are performed for two different truncated cones by impacting them on a "rigid" wall, termed a sensing plate which enables us to measure the impulsive force produced by the collision. The theoretical predictions are found to be in good agreement with the experimental results.
