Simulation de la conduction de la chaleur dans un milieu continu par un modèle éléments discrets

Abstract

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 [1], explains how to simulate heat conduction through a continuous material using a discrete model of the domain.
