Abstract
This paper presents a numerical simulation for the propagation of tors ional waves in an elastic-viscoplastic stepped bar subjected to torsio nal impact at its end surface. The equations governing the dynamic tor sional deformation of the stepped bar are solved by means of the metho d of numerical integration along bicharacteristics. The stability and convergence of the present numerical technique are investigated by exa mining the error in the total energy of the numerical solution as time increases.
