Discrete element method (DEM) simulation to improve performance of a mouldboard skimmer
Soil and Tillage Research, 2021Abstract Historically, most mouldboard plough research has been focused on improving the performance of the mouldboard itself, with very little focus on other plough components such as the skimmer. The skimmer is a critical additional component of the overall mouldboard plough which affects its performance in the field.

Simulation of the Slump Test Based on the Discrete Element Method (DEM)
Advanced Materials Research, 2012The slump test is a very important industrial test for evaluation of workability of fresh granular-cement paste material, especially concrete. The test method is used as a generic tool for classification of a wide range of mixtures and can deal with a wide range of workabilities.

Application of the Discrete Element Method (DEM) on Ship-Ice Interaction
SNAME 10th International Conference and Exhibition on Performance of Ships and Structures in Ice, 2012Sailing through ice requires modifications to the standard ship form in terms of structural strength and hull lines. For ships that sail through light ice or brash ice channels, assisted where necessary by an icebreaker, the challenge lies in striking a balance between optimizing the hull for open water and ice conditions, bearing in mind the ...

Comparison of Two Subsoiler Designs Using the Discrete Element Method (DEM)
Transactions of the ASABE, 2018Abstract. Subsoiling is an essential tillage practice for loosening soil and enhancing water infiltration. In this study, a discrete element model was developed and validated to simulate soil-tool interactions. The validated model was then used to evaluate two design alternatives of subsoiling tool: a non-winged tool (NW) and a winged tool (WW).

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

Modeling of soil–claw interaction using the discrete element method (DEM)
Soil and Tillage Research, 2016Bionics can be applied in the area of designing soil engaging tools in agriculture to minimize power requirement and optimize soil conditions for crop growth. In this study, a bear claw was investigated with the objective of mimicking it for the future design of subsoiling tools.

Simulation of Fresh Concrete Flow Using Discrete Element Method (DEM)
2014The behaviour of fresh concrete during its mixing, transport, placement, and compaction can ultimately have significant effects on its mechanical performance, durability, surface appearance, and on its other properties after hardening. In concrete construction many problems result from the improper filling of formwork, insufficient de-airing, concrete ...

Modeling the Behavior of Spherical Particles Using the Discrete Element Method (DEM)
Materials Science ForumThe article discusses the application of the discrete element method (DEM) for modeling the behavior of spherical particles in granular media. Key aspects of particle contact interactions, including frictional forces, elasticity, coordination number, and the shape factor of spherical particles, are analyzed and investigated. It is worth noting that the
