Abstract: Voronoi tessellations are commonly used in discontinuum numerical models to simulate the microstructure of brittle rocks. In this approach, the model domain is divided into several randomly generated polygonal blocks. Discontinuum-based Voronoi Tessellated Models (VTM) capture the brittle rock failure process more realistically than conventional continuum models. However, their higher computational costs often limit their practicality. This paper presents the applications of a continuum-based VTM for simulating brittle rock damage and failure at core and rock mass scales. The examples reviewed include: 1) laboratory behavior of a marble; 2) drilling-induced core damage; 3) failure mechanism of hard rock pillars; and 4) v-shaped notch formation around a circular tunnel. It is concluded that a properly calibrated continuum-based VTM can be used as a reliable tool for analyzing a wide range of geomechanical problems.
