The aim of this method is for solving a class of problems that cannot be treated by continuous or analytical approaches such as packing problems or hourglass flows of granular media. In addition to this historical use, a part of the DEM scientific community focuses on a class of particular problems which are generally treated by continuum mechanics based method such as Finite Element Method (FEM). More particularly, an intensive research area concerns cracking phenomena including diffuse cracking, localization, crack branching or fragmentation that occurs within brittle or quasi-brittle media such as polymer composites, rocks, concrete, glasses or ceramics. Nevertheless, using the DEM in such a context of continuum mechanics is not obvious for two because many the input parameters of the DEM model needs to be calibrated. The present study proposes to deal with this scientific bottleneck. A new DEM model implemented in the open source DEM GranOO software is presented which is able to deal with continuum mechanic constitutive laws implemented in Kratos such as damage, plasticity and orthotropic behaviors.<\/p>\n<h5 class=\"cimne blue-background\" style=\"float: none;padding-left: 15px\">SPEAKER CV<\/h5>\n<p><strong>Damien Andr&eacute;.<\/strong> Associate professor, Ceramics Research Institute (IRCER), Limoges University, France<\/p>\n<p>Since its PhD, defended in 2012, Damien Andr&eacute;&#039;s research activities are mainly involved in numerical methods for applied mechanics dedicated to brittle materials. He co-develops original numerical methods, algorithms and models within the discrete element framework named GranOO in order to improve the understanding and the prediction of the microstructure \/ macroscopic properties relationships of ceramics and, more specifically, refractory materials using thermo-mechanical approaches.
