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 implemented contact constitutive model is an extension of the Fracture Energy Softening Model where the pre- and post-peak behavior of cohesive quasi-brittle materials subjected to various loading conditions is predicted via proposed fracture energy-based bi-linear elasto-softening behaviour.
