The combined plastic and discrete fracture deformation framework for finite‐discrete element methods
International Journal for Numerical Methods in Engineering, 2019The combined finite‐discrete element method (FDEM) was originally developed for fracture and fragmentation of brittle materials, more specifically for cementitious and rock‐like materials.

DISCRETE ELEMENT METHOD FOR MULTISCALE MODELING
Journal of Multiscale Modelling, 2010A discrete element method (DEM) has been developed to provide highly accurate and detailed predictions of the Lagrangian particle phase. Especially in this study, DEM has been used together with an Eulerian approach for the fluid phase to look at interphase exchange phenomena in a multiphase-multiscale modeling approach.

Modeling the interaction of soil and a vibrating subsoiler using the discrete element method
Computers and Electronics in Agriculture, 2020A vibrating subsoiler can effectively reduce the draft force compared to a rigid one. Several theoretical and experimental methods have been developed to study the interaction of soil and vibrating tools, enabling the exploration of the mechanism of a ...

DISCRETE FINITE ELEMENT METHOD
Engineering Computations, 1992A numerical technique is described for the analysis of multiple interacting deformable bodies undergoing large displacements and rotations. Each body is considered an individual discrete unit, which is idealized by a finite element model. Discrete finite element models interact with their surroundings through contact stresses, which are continually ...

Engineering Computations, 2004
Discrete element method (DEM) has been extensively used in the laboratory of particulate and multiphase processing at the University of New South Wales (UNSW) to study the fundamentals of particulate matter at a particle scale. This paper briefly reviews the work in the laboratory, which covers the development of simulation techniques and their ...

Evaluation of an FPGA Implementation of the Discrete Element Method
2001The Distinct Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles, and is widely used for process optimisation in the food and pharmaceutical industries. The DEM is very computationally expensive, but has properties that make it amenable to acceleration by reconfigurable computing ...
