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.
The webinar introduces a workflow to digitize and simplify ballast stones, grain shape quantification systems, different contact treatment and breakage models and their application in PFC3D to simulate large scale shear box tests.
The shape of the individual stones in railway ballast has a significant impact on the mechanical behaviour of the track bed. Convex rigid blocks allow to model grains with good accuracy while maintaining reasonable computational demand.
