The overturning of Riemann waves in elastoplastic media with hardening. (English. Russian original) Zbl 1432.74042

Summary: Riemann waves (simple waves) are investigated within the von Mises elastoplasticity model with hardening. It is assumed that preceding processes have brought the medium into a state corresponding to a certain point on the loading surface. The conditions under which a Riemann wave overturns during its evolution, i.e., the conditions for the formation of discontinuities, are indicated.
