    Abstract:
    Similarity solutions for the steady state equations governing flow of granular materials under gravity in a conical or wedge-shaped hopper are constructed. Such solutions can be considered for various plasticity models. Results obtained under the classical Mohr-Coulomb yield condition are compared with those obtained when a von Mises yield contidion is imposed. A thorough stability study in the case of the Mohr-Coulomb materials, for which several important simplifications take place, is proposed.
