Fracture characteristics based on discrete element method [PDF]
Youqicang 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 ...

Simulating Fractures With Bonded Discrete Element Method [PDF]
IEEE 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
The 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
Applied 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.

A variational integrator for the Discrete Element Method [PDF]
Journal 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.
