AXIAL PLASTIC WAVES IN A ROD

Equations are presented to describe nonlinear plastic wave propagation in a rod with the effects of radial inertia and radial shear included . Intrinsic constitutive equations are postulated for plastic deformat ion, and some of the principal aspects of wave propagation are describ ed. In particular, a scaling argument is used to extract the nonlinear bar speed, which carries the principal pulse of energy, rather than t he two characteristic speeds. (C) 1998 Elsevier Science Ltd.
