Geomechanica at ARMA 2015
Posted by

Geomechanica is looking forward to presenting some recent research and development at the 49th US Rock Mechanics/Geomechanics Symposium (ARMA 2015) External link, to be held at the Westin St. Francis in San Francisco, California, from June 28 to July 1, 2015.


On Saturday June 27, 2015, Dr. Bryan Tatone will be offering a short course External link on the use of the hybrid finite-discrete element method (FEMDEM) to simulate fracture processes in rocks. The course will cover the theoretical principles of the numerical method and will offer the opportunity to gain valuable “hands-on” experience using Geomechanica’s pre-released Irazu FEMDEM software External link. We encourage petroleum, mining, geological and geotechnical engineers, graduate and post-graduate students with an interest in brittle rock behaviour to attend this short course.


The complete conference technical program can be found here External link. The topics of our oral presentations deal with the numerical simulation of hydraulic fracturing, discontinuity shearing behaviour, rock reinforcement, and thermo-mechanical wellbore instability within an FEMDEM framework. The specific titles include:

  • Paper 299 – 3D simulation of fluid-pressure-induced fracture nucleation External link
  • Paper 302 – Verification of the implementation of rock-reinforcement elements in numerical analyses based on the hybrid combined finitediscrete element method (FDEM) External link
  • Paper 304 – A combined experimental (micro-CT) and numerical (FDEM) methodology to study rock joint asperities subjected to direct shear External link
  • Paper 421 – FDEM modelling of thermo-mechanical wellbore instabilities within shale formations External link
