Application of Breakage Models to Particle Speeds Simulated by Discrete Element Methods [PDF]
Journal of Applied and Computational MechanicsSimulations that calculate the breakage of a given material allow for estimating the particle size produced by comminution equipment. However, conducting these simulations requires a significant amount of time and incurs high computational costs due to ...

The soft discrete element method
Granular Matter, 2021 In order to accelerate simulations of assemblies of highly deformable grains, a novel numerical approach, called Soft Discrete Element Method (SDEM) is presented. It consists in extending the classical DEM by introducing the deformability of the grains in a simplified way.

Development of a GPGPU‐parallelized hybrid finite‐discrete element method for modeling rock fracture
International journal for numerical and analytical methods in geomechanics (Print), 2019 The hybrid finite‐discrete element method (FDEM) is widely used for engineering applications, which, however, is computationally expensive and needs further development, especially when rock fracture process is modeled. This study aims to further develop

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

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.
