NUMERICAL MODELLING OF DISCONTINUOUS ROCK MASS IN THE PLASTIC DOMAIN

The paper deals with the problem of discontinuous ruck material modelling within the framework of theory of plasticity. The applicability of two models, i.e. Mohr-Coulomb's ideal plasticity and plastic anisotropy (ubiquitous joint model), is examined. Numerical analyses were performed with FLAC...

Description
Summary:The paper deals with the problem of discontinuous ruck material modelling within the framework of theory of plasticity. The applicability of two models, i.e. Mohr-Coulomb's ideal plasticity and plastic anisotropy (ubiquitous joint model), is examined. Numerical analyses were performed with FLAC - finite difference code. The comparision of above mentioned constitutive models is made through the demonstrated mechanical behaviour in the direct shear test (the paper is published in Croatian).
