Abstract : A few numerical comparisons are made on the stresses, strains and velocities in a rod whose end is subjected to a sudden velocity impact. The computations made are based on three different theories: (1) the von Karman plastic wave theory, (b) the Malvern theory which considers a strain rate proportional to the dynamic stress excess over static stress, and (c) the strain-rate theory of Prandtl which predicts an exponential relationship between strain rate and dynamic stress excess.
