An Experimental Study of the Propagation of Transient Longitudinal Deformations in Elastoplastic Media

Abstract

The propagation process of longitudinal plastic pulses in prestrained bars has been studied to test the validity of the Donnell-Taylor-von Kármán theory of plastic waves. The results obtained for the propagation velocity and wave-shape changes indicate that the theory fails to describe the dynamic process by its neglect of strain-rate and creep effects.
