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.
Cable elements in 3DEC may be assigned a tensile yield force limit and an axial rupture strain in order to simulate cable rupture. 3DEC can also simulate the shearing resistance along the cable length between the grout and either the cable or the host material.
3DEC 5.2 adds a number of new features for cable bolts, including enhanced information querying and visualization.
This video shows a cross-section of a tunnel with the rock displacements (gray-scale) indicating ground damage and bulking, cable axial forces (bar chart), and cable state.
