We recently hosted a webinar to provide an overview of the latest features of Irazu version 6.1 in action. We also demonstrated two practical applications of Irazu, including a slope stability problem using the new time-varying, user-imported water table profiles, as well as a tunnel excavation model with mixed FEM and FDEM material models. For … Read more
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
Following up from our previous blog post on 3D FEMDEM Simulations, 3D simulations of a tunnel excavated in a weak rock (resembling properties of a clay shale) are presented here (E=3.8 GPa, ν=0.25, σt=0.41 MPa, c=5 MPa). In this simplified case study, the entire length of the tunnel was excavated at once at the beginning … Read more
We have been working on a prototype of three-dimensional FDEM. We’ve implemented most of the critical features into the code, including a quasi-static friction law, Mohr-Coulomb failure criterion, and transversely isotropic elastic constitutive law. We’re excited to showcase some of the simulations results here. The figure below shows the simulation of a uniaxial compression test … Read more
