Dynamics of Granular Systems
نویسندگان
چکیده
Granular media are dissipative systems. The collisions between the grains are inelastic and therefore energy is intrinsically lost within the system while it is in motion. In order to explore some of the fundamental resulting effects on the statistical properties of such systems, let us idealize a granular medium by a set of N spherical particles, all being identical and having only the exclusive volume hard-core potential as interaction. In addition, one can imagine the particles to rotate and to be able to transfer angular momentum from one to the other during the collision. In that case, it is important to consider also the tangential frictional properties and the tangential dissipation. The inelastic properties are well described by the restitution coefficient material constants. For the time being let us ignore gravity.

SYSTEM MODELING WITH FUZZY MODELS: FUNDAMENTAL DEVELOPMENTS AND PERSPECTIVES
In this study, we offer a general view at the area of fuzzy modeling and fuzzymodels, identify the visible development phases and elaborate on a new and promisingdirections of system modeling by introducing a concept of granular models. Granularmodels, especially granular fuzzy models constitute an important generalization of existingfuzzy models and, in contrast to the existing models, generat...
متن کاملEfficient numerical simulation of granular matter using the Bottom-To-Top Reconstruction method
The numerical simulation of granular systems of even moderate size is a challenging computational problem. In most investigations, either Molecular Dynamics or Event-driven Molecular Dynamics is applied. Here we show that in certain cases, mainly (but not exclusively) for static granular packings, the Bottom-to-top Reconstruction method allows for the efficient simulation of very large systems....
متن کاملSlow relaxation and compaction of granular systems.
Granular materials are of substantial importance in many industrial and natural processes, yet their complex behaviours, ranging from mechanical properties of static packing to their dynamics, rheology and instabilities, are still poorly understood. Here we focus on the dynamics of compaction and its 'jamming' phenomena, outlining recent statistical mechanics approaches to describe it and their...
متن کاملNumerical Simulation of Granular Column Collapses with Pressure-Dependent Viscoplastic Model using the Smoothed Particle Hydrodynamic Method
This paper presents a numerical analysis of granular column collapse phenomenon using a two-dimensional smoothed particle hydrodynamics model and a local constitutive law proposed by Jop et al. This constitutive law, which is based on the viscoplastic behaviour of dense granular material flows, is characterized by an apparent viscosity depending both on the local strain rate and the local press...
متن کاملReliability analysis of repairable systems using system dynamics modeling and simulation
Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...
متن کاملUniversal slip dynamics in metallic glasses and granular matter – linking frictional weakening with inertial effects
Slowly strained solids deform via intermittent slips that exhibit a material-independent critical size distribution. Here, by comparing two disparate systems - granular materials and bulk metallic glasses - we show evidence that not only the statistics of slips but also their dynamics are remarkably similar, i.e. independent of the microscopic details of the material. By resolving and comparing...
