MatDEM-fast matrix computing of the discrete element method

open access: yesEarthquake Research Advances, 2021
Discrete element method can effectively simulate the discontinuity, inhomogeneity and large deformation and failure of rock and soil. Based on the innovative matrix computing of the discrete element method, the high-performance discrete element software ...

A Fully Discrete Evolving Surface Finite Element Method [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2012
In this paper we consider a time discrete evolving surface finite element method for the advection and diffusion of a conserved scalar quantity on a moving surface. In earlier papers using a suitable variational formulation in time dependent Sobolev space we proposed and analyzed a finite element method using surface finite elements on evolving ...

Fracture characteristics based on discrete element method [PDF]

open access: yesYouqicang pingjia yu kaifa, 2023
In order to explore the characteristics of fracturing fractures of shale with weak plane development, a fracture propagation model of shale reservoirs taking the weak plane of bedding and natural fractures into account is established by the three ...

A variational integrator for the Discrete Element Method [PDF]

open access: yesJournal of Computational Physics, 2022
A novel implicit integration scheme for the Discrete Element Method (DEM) based on the variational integrator approach is presented. The numerical solver provides a fully dynamical description that, notably, reduces to an energy minimisation scheme in the quasi-static limit.

Simulating Fractures With Bonded Discrete Element Method [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2022
Along with motion and deformation, fracture is a fundamental behaviour for solid materials, playing a critical role in physically-based animation. Many simulation methods including both continuum and discrete approaches have been used by the graphics community to animate fractures for various materials.

Accelerating Polyhedral Discrete Element Method with CUDA

open access: yesThe Astronomical Journal, 2023
This paper presents an efficient CUDA-based implementation of a nonspherical discrete element method where irregular particles are described by using polyhedrons. Two strategies are employed to exploit the parallelism of the numerical method.

Segregation Modeling in Stockpile Using Discrete Element Method

open access: yesApplied Sciences, 2022
During stockpile feeding, the small particles migrate to the center of the stock while large particles end up around the edges. This phenomenon influences how the mineral is fragmented in the subsequent stages of size reduction.
