ARMA 2017: Short Course on 2D and 3D Modeling of Rock Fracturing Processes in Geomechanics
Posted by

Geomechanica is looking forward to teaching a short course on 2D and 3D Modeling of Rock Fracturing Processes in Geomechanics at the 51st US Rock Mechanics/Geomechanics Symposium (ARMA 2017) to be held in San Francisco, California, USA on 25-28 June 2017 . The one-day course, instructed by Dr. Bryan Tatone and Mr. Aly Abdelaziz will Read More >>>



 
FEM Solver
Posted by

The computational engine of Irazu simulation software is based on the finite-discrete element method. This inherently means that Irazu is equipped with a finite element solver (FEM). The FEM solver uses linear elastic constitutive laws (isotropic and transversely isotropic) and solves the equations of motion using an explicit time integration scheme. Therefore, it is well Read More >>>



 
Numerical simulation of discontinuity shearing behaviour
Posted by

The multi-facetted experimental and numerical investigation forming the PhD thesis of Geomechanica’s Dr. Bryan Tatone entitled “Investigating the evolution of rock discontinuity asperity degradation and void space morphology under direct shear ” demonstrated the first experimentally-supported simulation of discontinuity shearing using a FDEM modelling approach. Dr. Tatone’s work coupled micro-Computed Tomography (micro-CT) with FDEM modelling Read More >>>

Video demo of Irazu to simulate hydraulic fracturing
Posted by

Irazu is an advanced general-purpose rock deformation and fracturing simulation software. In this video, an application of Irazu to simulate fluid injection into a permeable, fractured rock mass is presented (i.e., hydraulic fracturing). The software is capable of capturing: fluid-driven fracturing of intact rock; energy dissipation due to fluid viscosity and fracture toughness; fluid leak-off Read More >>>



 
A new fully-coupled hydro-mechanical formulation for the Irazu software
Posted by

We are excited to announce that we have been working on the introduction of hydro-mechanical (H-M) coupling in our Irazu FDEM software. The introduction of H-M coupling arguably makes the Irazu software one of the most sophisticated simulation software currently available for geomechanical applications as a multitude of multi-physics processes can be taken into account, Read More >>>



 
A pragmatic methodology to abstract the EDZ around tunnels of a geological radioactive waste repository
Posted by

Geomechanica is launching a guest blog series, written by experts and numerical modellers in the field of rock engineering. In the first post of this series, we’re showcasing the work of Andrés Alcolea on “A pragmatic methodology to abstract the EDZ around tunnels of a geological radioactive waste repository – Application to the HG-A experiment Read More >>>
