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 presents the validation of the mixed continuum-discrete FEM-DEM approach. It is done by modeling, using FLAC3D and PFC3D ITASCA software, pseudo-static experiments carried out on scaled-down rockfill dams with dry-stone pitching.
A numerical model of a full-scale dam is then built using this validated approach. The construction phases and reservoir filling processes are modeled. Then, the dam seismic resistance is evaluated by performing pseudo-static tests provided by tilting the dam until failure.
Presenter: Mr. Ali Haidar
Ali Haidar finished his Master in Civil Engineering at the Lebanese University, Faculty of Engineering in Beirut, Lebanon. Then, he pursued his Master 2 in “Hydraulics and Civil Engineering” at Grenoble INP-ense3 in Grenoble, France in where he did his Master's internship at INRAE in Aix-en Provence, France. He joined ITASCA as a Junior Researcher Civil Engineer to start his Ph.D. in Collaboration with “Ecole Centrale de Lyon” and “Electricité de France”. His work will focus on the Seismic behavior of rockfill dams with a dry stone rip-rap. He will use mixed DEM-FEM numerical modeling by coupling between ITASCA Software: PFC3D and FLAC3D.
