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 >>>



 
Irazu computational performance
Posted by

Irazu makes use of state-of-the-art high performance computing techniques to speed-up computations. In particular, we use GPU (graphics processing unit) computing on consumer-grade AMD graphics cards. To demonstrate the improvement in computation speed, five uniaxial compression strength (UCS) tests with an increasing number of finite elements were simulated using Irazu and the sequential CPU code 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 >>>



 
Simulation of thermally-induced fracturing
Posted by

Understanding and predicting the the rock mass mechanical response to temperature variations is relevant for a number of geo-engineering applications, including: underground disposal of nuclear waste, geothermal energy extraction, underground LNG storage, geological sequestration of CO2, and coal bed gas extraction. We are pleased to announce that we have been working on the introduction of Read More >>>



 
FEMDEM model calibration
Posted by

The ability to capture increasingly complex behaviours within a numerical simulation is typically accompanied by an increase in the number of input parameters that must be specified. Inevitably, with additional physics come additional parameters to govern these physics. Critics of numerical modelling often cite the uncertainty associated with parameter selection as a reason to avoid Read More >>>



 
A new FEMDEM modelling capability: rock reinforcement
Posted by

We are excited to announce that we have implemented a mechanically-based model of the rock-reinforcement interaction process. The methodology represents an adaptation of the reinforcement elements first developed for FEMDEM analysis of reinforced concrete (Zivaljic et al. 2013) and modified to make them suitable for modelling rock masses. From a numerical viewpoint, the reinforcement model Read More >>>
