A bonded-particle model for cemented sand (2013, background): “still faithfully reproducing the macroscopic response of the material [53].”
Extended CFD–DEM for free‐surface flow with multi‐size granules (2016, background): “For instance, the pressure-based buoyancy force exerted on a particle measuring Vp in volume is Vp( ∇p+∇ τ), which has been implicitly integrated into the momentum equation of fluid after replacing Vp with (1 αf) [8, 25].”
A poly‐superellipsoid‐based approach on particle morphology for DEM modeling of granular media (2019, background): “Benefiting from the convexity of a poly-superellipsoid, we can construct a one-to-one mapping function S(n) from a surface outward normal vector n(nx,ny,nz) to a surface point p(x, y, z) of a poly-superellipsoid with Equations (2a) to (2c) and (3a) and (3b), ie, p = S(n).”
The influence of inter-particle friction and the intermediate stress ratio on soil response under generalised stress conditions (2012, background): “Such boundaries are widely used in geotechnical engineering and details for their implementation can be found elsewhere [2,10].”
Imposition of essential boundary conditions in the material point method (2018, methodology): “Remeshing and Interpolation Technique with Small Strain (RITSS) [4] which is itself still mesh-based, the Discrete Element Method (DEM) [5] (computationally expensive for real-world geometries) or Smoothed Particle Hydrodynamics (SPH) [6] which has difficulties with solid material modelling.”
Behavior of fresh and fouled railway ballast subjected to direct shear testing: discrete element simulation (2014, background): “…Lobo-Guerrero and Vallejo 2006; Lu and McDowell 2006; Hossain et al. 2007; Sitharam and Vinod 2008; Sitharam and Vinod 2009; Huang et al. 2009b; Thakur et al. 2010; Indraratna et al. 2010a; Wang and Gutierrez 2010; O’Sullivan et al. 2008; O’Sullivan and Cui 2009; O’Sullivan 2011), among others.”
