Discrete element method approach to modelling VPP dampers

open access: yesMATEC Web of Conferences, 2018
In this paper, we present a novel approach to modeling and analysis of Vacuum Packed Particle dampers (VPP dampers) with the use of Discrete Element Method (DEM). VPP dampers are composed of loose granular medium encapsulated in a hermetic envelope, with

A review of discrete modeling techniques for fracturing processes in discontinuous rock masses

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2014
The goal of this review paper is to provide a summary of selected discrete element and hybrid finite–discrete element modeling techniques that have emerged in the field of rock mechanics as simulation tools for fracturing processes in rocks and rock ...

Hybrid Finite-Discrete Element Modelling of Excavation Damaged Zone Formation Process Induced by Blasts in a Deep Tunnel

open access: yesAdvances in Civil Engineering, 2020
A brief literature review of numerical studies on excavation damage zone (EDZ) is conducted to compare the main numerical methods on EDZ studies. A hybrid finite-discrete element method is then proposed to model the EDZ induced by blasts.

Parallel coupling strategy for multi-physics applications in eXtended Discrete Element Method [PDF]

open access: yes, 2020
Multi-physics problems containing discrete particles interacting with fluid phases are widely used industry for example in biomass combustion on a moving grate, particle sedimentation, iron production within a blast furnace, and selective laser melting ...

Track ballast modelling by discrete element method

open access: yesGrađevinar, 2019
An increase in axle load and travel speed causes faster degradation of track structure and, hence, of the ballast prism. Crushing of stone grains in ballast due to excessive contact forces among these grains causes degradation in the form of filling of ...

From discrete particles to solids – about sintering and self-healing [PDF]

open access: yesComputer Methods in Materials Science, 2011
In this review, particulate materials are studied using the Discrete Element Method (DEM), where the particles keep their identity throughout. Loose particles can sinter due to time-, stress- or temperature-dependent forces.

A Dual-Horizon Peridynamics–Discrete Element Method Framework for Efficient Short-Range Contact Mechanics

open access: yesModelling
Short-range forces enable peridynamics to simulate impact, yet it demands a computationally expensive contact search and includes no intrinsic damping.

Slope Failure of Noncohesive Media Modelled with the Combined Finite–Discrete Element Method

open access: yesApplied Sciences, 2019
Slope failure behaviour of noncohesive media with the consideration of gravity and ground excitations is examined using the two-dimensional combined finite⁻discrete element method (FDEM).

Finite element method–discrete element method bridging coupling for the modeling of gouge

open access: yesInternational Journal for Numerical Methods in Engineering, 2022
AbstractWe discuss the multiscale modeling of a granular material trapped between continuum elastic domains. The amorphous granular region, usually termed “gouge,” is under high confinement pressure, to represent the loading of faults at depth. We model the granularity of gouge using the discrete element method (DEM), while the elastic regions ...
