A COMPARISON OF PLASTIC LONGITUDINAL WAVE THEORIES FOR STRAIGHT RODS,

reportActive / Technical Report | Accession Number: AD0658148 | Need Help?

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.
