Effect of aggregate structure on fracture process in concrete using 2D lattice model (2007, methodology): “Within discrete methods, the most popular ones are: classical particle DEM [ 15 ,18], interface element [12] and lattice methods [21,28,39,44,48,49].”
Polygon‐based contact resolution for superquadrics (2006, background): “Although polygon is one of the basic geometric entities, its application in discrete element simulations of engineering problems has been limited [7–9].”
A bonded-particle model for rock (2004, background): “) or separate particles bonded together at their contact points and utilize the breakage of individual structural units or bonds to represent damage [19–22].”
A bonded-particle model for cemented sand (2013, background): “Some authors use non-spherical particles to model the bonded material [33,34].”
On the effect of ITZ thickness in meso-scale models of concrete (2020, methodology): “Moreover, some works use the Discrete Element Method (DEM) to simulate concrete material, where ITZs are either modelled with contact elements [27] or by connecting beams or springs [2,50,51].”
Lattice Element Models and Their Peculiarities (2017, background): “D’Addetta and coauthors [67, 68] developed the discrete lattice model with Voronoi cells as randomly shaped convex polygons which represents material grains, and where both static and dynamic equations of motion are solved.”
A 2D polygon/polygon contact model: algorithmic aspects (2004, methodology): “The contact interaction laws are normally developed within the framework of penalty methods which only approximately satisfies the contact displacement constraints, thereby allowing a small amount of overlap to occurPolygons are one of the basic geometric entities employed in the DEM, but their appl”
Comparative study of different discrete element models and evaluation of equivalent micromechanical parameters (2012, methodology): “, 1994), is also commonly used in calibration of discrete element models (D’Addetta et al., 2002; Fakhimi and Villegas, 2007; Rojek et al., 2011; Ng, 2006; Huang, 1999; Potyondy and Cundall, 2004; Huang and Detournay, 2008).”
A bond model for DEM simulation of cementitious materials and deformable structures (2014, background): “A strut model only resists the axial force, but is simple to implement and fast for computation; beam models are more computationally expensive but provide more realistic representations of the bond mechanism as they can take into account axial, bending, shear and torsion behaviour at a cemented joi”
