The Discrete Element Methods are the most appropriate methods to model the divided feature of some media such as granular ones, masonries or contact interfaces... Many studies have provided a better understanding of their behavior, but in some cases the impact of both volume description (rigid or deformable) and interaction laws (elastic or plastic) is not negligible on the global behavior. The approach used here is based on the "Non Smooth Contact Dynamic" framework which mixes naturally the rigid and deformable formulations. One propose to analyze the influence of this description. For this purpose, two different applications are used, related to the quasi-static behavior of granular media and to the modelization of the tribological int...
