Abstract

Cross Bond Discrete Element Method (XB-DEM) was developed as a new simulation model for analyzing the deformation and breakage behavior of particles. A key feature of XB-DEM is that the parameters correlated with the deformation and breakage behavior of particles can uniquely be determined by single particle compression tests. In XB-DEM, a particle was represented by a cluster of constituent particles whose center and surface vicinity were connected with the bond units that have the same components. The bond unit was composed of a bond spring and a bond damper and ruptured when the extension of the bond unit exceeded the rupture extension. Consequently, the parameters that correlated with the deformation and breakage behavior of the particles were only the bond spring coefficient and the rupture extension of the bond unit, considering that the bond damper coefficient was set to achieve critical damping. It was confirmed that the parameters of XB-DEM can be determined by the slope and breakage displacement of load–displacement diagrams of single particle compression tests. Furthermore, the deformation and breakage behavior of the simulated particles coincided with the experimental observations, and the simulated load–displacement diagrams quantitatively agreed with the measured ones.

期刊介绍： The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
