Modeling of soil–claw interaction using the discrete element method (DEM)

Soil and Tillage Research, 2016
Bionics 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)

2014
The 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 ...

Simulation of Asphalt Concrete Uniaxial Creep Using Discrete Element Method (DEM)

Pavements and Materials, 2010
In this paper, a methodology for modeling creep behavior of asphalt concretes (AC) under uniaxial static loading is presented. Three AC mixtures were produced using Coarse Matrix High Binder type C (CMHB-C) mixture type. Three different aggregate sources, namely a Hard Limestone (HL), a Soft Limestone (SL), and a Granite (G) and a PG 76-22 binder were ...

Comparison of Two Subsoiler Designs Using the Discrete Element Method (DEM)

Transactions of the ASABE, 2018
Abstract. 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).

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, 2012
Sailing 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 ...

PART II—Discrete Element Method (DEM) Approaches: Dynamic Powder Deposition

2017
Dry powders require different modeling and simulation tools to characterize their behavior. One family of methods that is ideally suited to this task are discrete element methods. This chapter introduces the reader to this type of modeling.
