## Abstract A general form of the yield criterion derived from a special rateβtype constitutive equation for a granular material provides an appropriate yield surface over a narrow range of material parameters. The complete yield surface is described using a single equation.
Abatraet-The Nadai elastic-plastic boundary is introduced to d&e the core region, instead of a core region with a constant distance r from the crack tip and a core region with the Mises elastiqlastic boundary. Taking into account fracture parameters along the Nadai elastitiplastic boundary, two impr
