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.
The webinar introduces a workflow to digitize and simplify ballast stones, grain shape quantification systems, different contact treatment and breakage models and their application in PFC3D to simulate large scale shear box tests.
This webinar is for people who have used PFC before and are interested in the latest developments.
In this 30-minute webinar will different numerical modeling methods used in rock engineering be discussed. The talk will outline advantages and disadvantages of the different approaches, including continuum, discontinuum and hybrid solutions. Additionally, will examples showing the use of the different methods in real consulting projects be presented.
This webinar is for people who are new or occasional FLAC3D users, or those interested in learning more about it.
The webinar will present new tools available in 3DEC 7.0 to simplify and speed-up model construction.
This includes: building block models directly from arbitrary geometry data (imported from CAD), creating a grid that conforms to a topographic surface, an advanced meshing generator which provides greater control on the size of meshes at specific points and surfaces and allows mesh gradation within blocks, the capability to generate Voronoi blocks and many more features. The webinar will provide examples of applications and guidance on what meshing solution to choose depending on your problem.
Learn how 3D numerical simulations are useful to predict and investigate possible modes of fracture interference and clarify the underlying mechanisms.
This webinar by Dr. David Potyondy provides an overview of Bonded-Particle Modeling (BPM) and suggests avenues for further research. You need not be a rock-mechanics practitioner to understand this talk.
As part of the first ARMA Student Design Competition in 2021, this webinar will introduce the use of FLAC/Slope for slope stability analysis.
This webinar will review and demonstrate the Itasca Constitutive Model for Advanced Strain Softening (IMASS) which has been developed to represent the rock mass response to excavation induced stress changes.
Griddle 2.0 Has Been Released! Join us for a webinar on "What's New in Griddle 2.0?"
Lahars represent natural phenomena that can generate severe damage in densely populated urban areas. The evaluation of pressures generated by these mass flows on constructions (buildings, infrastructure…) is crucial for civil protection and assessment of the structures’ vulnerability. The existing tools developed to model the spread of flows at large scale in densely populated urban areas remain inaccurate in the estimation of mechanical efforts.
This webinar is for people who have used 3DEC before and are interested in the latest developments.
This webinar will demonstrate setting-up a hydraulic fracturing model in jointed rock using XSite. An overview of XSite and a discussion of the simulation results will also be discussed.
This webinar is for people who are new or occasional 3DEC users, or those just interested in learning more about it.
This webinar provides a brief overview of PFC modeling using convex rigid blocks, including example applications ranging from rock-mass behavior to granular flow, and highlights important tip and tricks and modeling challenges.
Learn about the major new features and improvements in FLAC3D version 7.0.
Presented by Dr. Peter A. Cundall: Numerical modeling is widely used in Geomechanics for design and diagnostic purposes, but there is an art to using the software tools correctly. It's not just a case of plugging in the data, and hitting "run". We need to understand the underlying physics, and whether the model properly represents it.
This video is a recording of a one hour webinar reviewing the latest features in Version 5.2 of 3DEC. Presented by Dr. Jim Hazzard, 3DEC Product Manager and Lead Developer. A petroleum geomechanics case study using 3DEC modeling is also presented by Dr. Melanie Grob.
