Experimental Methods in Chemical Engineering: Discrete Element Method—DEM
The Canadian Journal of Chemical Engineering, 2019The discrete element method (DEM) is a time‐driven simulation technique based on a Lagrangian description of particle motion that predicts the flow of granular matter and fine powders in conveying, mixing, drying, and heterogeneous gas‐(liquid)‐solids reactors.

Discrete Element Method (DEM) Contact Models Applied to Pavement Simulation
2014Pavement is usually composed of aggregate, asphalt binder, and air voids; rigid pavement is built with hydraulic cement concrete; reinforced pavement contains steel. With these wide ranges of materials, different mechanical behaviors need to be defined in the pavement simulation.

A discrete element method (DEM)-based approach to simulating particle breakage
Acta Geotechnica, 2021An approach for particle breakage simulation based on the framework of discrete element method was proposed in the current study. Convex polyhedron blocks were adopted as elementary particles for the complex particle shapes, and the variability of particle breakage strength is modeled using the invertible function method.

Modeling soil-bulldozer blade interaction using the discrete element method (DEM)
Journal of Terramechanics, 2020Abstract Limited studies have been conducted to establish scaling relationships of soil reaction forces and length scales of bulldozer blades using the Discrete Element Method (DEM) technique. With a DEM-based similitude scaling law, performance of industry-scale blades can be predicted at reduced simulation efforts provided a calibrated and ...

Prediction of screw conveyor performance using the Discrete Element Method (DEM)
Powder Technology, 2009Screw conveyors are used extensively in agriculture and industry for transporting and/or elevating bulk materials over short to medium distances. They are very effective conveying devices for dry particulate solids, giving good control over the throughput. Despite their apparent simplicity, the mechanics of the transportation action is very complex and

Discrete element method (DEM) numerical modeling of double-twisted hexagonal mesh
Canadian Geotechnical Journal, 2008Double-twisted hexagonal mesh is used in several fields of civil engineering (gabion structures, retaining nets against rockfalls, etc.). This paper presents an approach based on the discrete element method (DEM) to model this specific mechanical system.

Modelling of soil–seed contact using the Discrete Element Method (DEM)
Biosystems Engineering, 2014It has long been recognised that soil–seed contact is vital to seed germination, as good soil–seed contact promotes water transfer from soil to seed. However, until today, it has not been possible to quantify soil–seed contact, due to the non-homogeneous nature of agricultural soil.

Simulations of soil flow properties using the discrete element method (DEM)
Computers and Electronics in Agriculture, 2019Abstract Understanding soil flow properties is important for designing high-performance soil-engaging tools in agriculture. In this study, soil flow tests were conducted for a sandy loam soil using the lifting cylinder method to obtain the angle of repose (AOR) of the soil.
