2D combined finite‐discrete element method to model multi‐fracture of beam structures
Jani Paavilainen, Jukka Tuhkuri, Arttu PolojärviThe purpose of this paper is to present a 2D combined finite‐discrete element method (FEM‐DEM) to model the multi‐fracture of beam structures and an application of the method to…
On upscaling of discrete element models: similarity principles
Y.T. Feng, K. Han, D.R.J. Owen, J. LoughranThe main purpose of this paper is to derive a set of similarity principles for discrete element modelling so that a numerical model can exactly reproduce the physical phenomenon…
On the application of quaternion‐based approaches in discrete element methods
Scott M. Johnson, John R. Williams, Benjamin K. CookThough the problem of resolving translational motion in particle methods is a relatively straightforward task, the complications of resolving rotational motion are non‐trivial…
A hierarchical search algorithm for discrete element method of greatly differing particle sizes
John F. Peters, Raju Kala, Robert S. MaierA critical step toward an efficient contact detection algorithm is to localize the contact search to the immediate neighborhood of each particle. In particular, cell‐based…
An algebraic condition and an algorithm for the internal contact between two ellipsoids
Ibrahim Trabelsi, Maher Moakher, Cendrine Gatumel, Henri BerthiauxThe purpose of this paper is to present a new method for the detection and resolution of the contact point between two ellipsoids. Numerical simulations of ellipsoidal particles…
A poly‐ellipsoid particle for non‐spherical discrete element method
John F. Peters, Mark A. Hopkins, Raju Kala, Ronald E. WahlThe purpose of this paper is to present a simple non‐symmetric shape, the poly‐ellipsoid, to describe particles in discrete element simulations that incur a computational cost…
Estimating 3D particle motion from high‐speed video for simulation validation
Mathew Price, Garry MorrisonThe purpose of this paper is to present an image based method for estimating the 3D motion of rigid particles from high‐speed video footage (HSV). The computed motion can be used…
On the validation of DEM and FEM/DEM models in 2D and 3D
Jiansheng Xiang, Antonio Munjiza, John‐Paul Latham, Romain GuisesAs particulate systems evolve, sliding, rolling and collision contacts all produce forces that discrete element method (DEM) methods aim to predict. Verification of friction…
Large‐scale parallel discrete element simulations of granular flow
Jens H. Walther, Ivo F. SbalzariniThe purpose of this paper is to present large‐scale parallel direct numerical simulations of granular flow, using a novel, portable software program for discrete element method…
Industrial particle flow modelling using discrete element method
Paul W. ClearyThe purpose of this paper is to show how particle scale simulation of industrial particle flows using DEM (discrete element method) offers the opportunity for better understanding…
