Presentation

The discrete element method (DEM) is a numerical tool that has gained wider acceptance in the last decade as a practical platform for the analysis of geomechanical problems at multiple scales. Large displacements, breakage and fragmentation are features easily addressed within the method and of high significance in geohazard analysis. DEM models also reproduce a large variety of geomaterial response while needing relatively few input parameters.

Despite these advantages the method has also some drawbacks. A significant one is related to the first modeling steps: selecting model geometry, initializing state, calibrating parameters, etc are very time consuming activities. Procedures appear less systematic, and good practice rules less easy to come by than in other, more traditional, numerical methods. Problems ensue and sometimes are revealed only at a later stage, when the model results are being exploited.

This course aims to put DEM model building in geomechanics on a firmer ground. To this end it gathers a number of speakers, whose expertise covers several complementary aspects of the method (formulation, coding, application) and modelling platforms. The talks would offer a comprehensive and up-to-date perspective in the topic.

The course is most suitable for researchers and practitioners that have some previous acquaintance with DEM-based models and/or would like to increase their understanding of the possibilities and limitations of this powerful modelling tool.
