Study of deformation and failure in an anisotropic rock with a three-dimensional discrete element model

This paper is devoted to numerical analysis of deformation and failure of transversely isotropic rocks. A three-dimensional discrete element (DEM) model is proposed in the framework of the particle flow code (PFC). The anisotropic rocks are characterized by a matrix phase in which non-persistent wea...
