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.
A pebbled beam (P-beam) is defined as a string of spherical balls for which the beam contact model exists at all ball-ball contacts. A P-beam provides the structural behavior of a prismatic and bisymmetrical beam composed of isotropic, linear elastic material. A P-beam is defined by the string of balls, and the ball densities (used along with ball radii to obtain ball mass). The structural properties of a P-beam are defined by the properties of each beam contact model in the string.
