Some Recent Applications of the Discrete Element Method
Civil-Comp Proceedings, 1991Abstract The discrete element method is a powerful numerical technique for the stress analysis of certain classes of structure. It does not possess the generality of the finite element method but neither does it require massive computing power. It seems applicable to line structures where Saint Venant's principle is relevant and it produces second ...

Simulation of food mastication based on discrete element method
International Journal of Computer Applications in Technology, 2008The information on mastication and food sensory properties is usually collected by recording people' ingesting and chewing actions using electromyography, fluorography, cinephotography, videofluorography, ultrasonography and magnetic resonance imaging, and so on.

Discrete Element Method for Slope Stability Analysis
Journal of Geotechnical Engineering, 1992Limit equilibrium methods for slope stability analysis do not, in general, satisfy the overall equilibrium conditions; they must make assumptions regarding the inclination and location of the interslice forces. An alternative slope analysis based on the discrete element method is presented to avoid these drawbacks.

Asia-Pacific Journal of Chemical Engineering, 2019
AbstractFlow behavior of particles is simulated by means of discrete element method (DEM) in a screw conveyor. The gas flow is considered by the Euler model. The subgrid scale model turbulence model is applied to solve gas turbulence. A detailed description of the model equations applied has been presented.

An erosion model for the discrete element method
Particuology, 2017Abstract A shear impact energy model (SIEM) of erosion suitable for both dilute and dense particle flows is proposed based on the shear impact energy of particles in discrete element method (DEM) simulations. A number of DEM simulations are performed to determine the relationship between the shear impact energy predicted by the DEM model and the ...

A discrete version of the boundary element method
Engineering Analysis, 1984Abstract It is well known that several problems described by partial differential equations can be rewritten in terms of integral equations. For time independent problems, Fredholm integral equations are obtained, whereas time dependent problems give rise to Volterra integral equations.
