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.
This webinar about IMASS was presented by Dr. Ehsan Ghazvinian, a geomechanics engineer with Itasca Consulting Group and an experienced IMASS practitioner.The Itasca Constitutive Model for Advanced Strain Softening (IMASS) represents the rock mass response to excavation-induced stress changes.IMASS uniquely utilizes two softening (or residual) yield envelopes to model the damage around an excavation, slope, or caving process. It represents the progressive failure and disintegration of the rock mass from intact, jointed, and/or veined rock to a disaggregated, bulked material.IMASS is a constitutive model for use in both FLAC3D and 3DEC (versions 7.0 or later) and is sold as a separate option. Monthly or annual leases are available.
