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 PM4Silt plasticity model was developed and implemented by Boulanger and Ziotopoulou (2018) for representing low-plasticity silts and clays in geotechnical earthquake engineering applications. Model development emphasized approximating a range of undrained monotonic and cyclic loading responses of saturated low-plasticity silts and clays that exhibit stress-history normalized behaviors, as opposed to the responses of purely nonplastic silts and sands. PM4Silt is a stress-ratio and critical state controlled, bounding surface plasticity model that builds on the framework of the PM4Sand model.
