This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
This tutorial will guide you through how to create a fractured Synthetic Rock Mass (SRM) specimen.
Rock masses are complex systems composed of a rock matrix that may have heterogeneous material properties, often riddled with discontinuities (e.g., fractures, joints, faults, etc.). With PFC, SRM modeling consists of superimposing fracture information (i.e., geometries and properties), from a discrete fracture network (DFN), onto a bonded-particle model (BPM). The BPM is used to model intact rock, and the mechanical behavior of the fractures is introduced by modifying the particle contacts intercepting fractures. As PFC models are inherently discrete, failure can occur both in intact BPM regions and along the fracture planes. The simulation of a rock mass from such a configuration is known as the Synthetic Rock Mass (SRM) methodology.
