Abstract
By use of three basic paths of elastic-plastic loading, a Riemann solv er is established for the one-dimensional combined longitudinal and to rsional stress wave problem of the thin-walled elastic-plastic tube. B ased on this, a second-order Godunov method is developed for the numer ical computation of elastic-plastic waves. Finally the numerical metho d is applied to some basic problems with known exact solutions and the comparison of results is made.
