Simulation de la conduction de la chaleur dans un milieu continu par un modèle éléments discrets
Communication avec acte
Discrete Element Method (DEM) uses a set of discrete elements in order to describe the material under study. The reason is that originally it was conceived to describe granular materials. Thus is naturally adapted to simulate problems like, for example, dry contact, fracturation and mixing. Nevertheless, modelling of a continuous zone may be useful in some of those problems. In that case, the correct physical behaviour of the continuous zone must be ensured. This work, based on the article by W. L. Vargas , explains how to simulate heat conduction through a continuous material using a discrete model of the domain.

Discrete element method, a tool to investigate complex thermo mechanical behaviour: application to friction stir welding Article dans une revue avec comité de lectureTERREROS, Inigo; CHARLES, Jean-Luc; COUPARD, Dominique; TCHERNIAEFF, Serge; IORDANOFF, Ivan (Springer Verlag, 2009)In material forming or cutting, the contact zone between the tool and the working piece is often very difficult to analyse because of diverse local phenomena. In the special case of FSW, a specific difficulty is the study ...
Article dans une revue avec comité de lectureCurrently, almost all material manufacturing processes are simulated using methods based on continuum approaches such as the Finite Element Method (FEM). These methods, though widely studied, face di culties with multi- ...
Discrete-element modelling of the grinding contact length combining the wheel-body structure and the surface-topography models Article dans une revue avec comité de lectureOSA, Jean-Louis; SANCHEZ, José Antonio; ORTEGA, Naiara; CHARLES, Jean-Luc; IORDANOFF, Ivan (Elsevier, 2016)Phenomena governing the grinding process are largely related to the nature and evolution of contact between grinding wheel and ground component. The definition of the contact area plays an essential role in the simulation ...
