The difference schemes which are obtained by averaging characteristic relationships on simplexes located in the characteristic hyperplanes are considered and investigated in the case of the hyperbolic system of equations which describe the propagation of waves in an elastoplastic medium. A method is proposed for approximating the so-called “geometric terms” in the case of axially symmetric problems.
