A bond model for DEM simulation of cementitious materials and deformable structures (2014, background): “The use of beam elements to represent cementitious materials may also be found in regular [15, 16] or random [17] lattice models.”
Mesoscale models for concrete: homogenisation and damage behaviour (2006, methodology): “The lattice model was extended by Lilliu and van Mier [54] for three-dimensional analyses.”
Effect of aggregate structure on fracture process in concrete using 2D lattice model (2007, methodology): “The obtained outcomes from numerical experiments for uniaxial tension are qualitatively in agreement with numerical solutions given in [28, 45, 46].”
Meso-scale computational modeling of the plastic-damage response of cementitious composites (2011, background): “Lilliu and vanMier [24] developed a 3D lattice model in order to solve the problem of brittleness of concrete, and reported that the 3D lattice model represents the more ductile behavior than the 2D lattice model.”
Confinement-shear lattice CSL model for fracture propagation in concrete (2006, background): “A recent three-dimensional version of the model [21] improves some shortcomings but still cannot simulate at the same time tensile fracture, uni- and biaxial compression failures, and over-hardening response to hydrostatic pressure and uniaxial compression strain.”
A new open-source software developed for numerical simulations using discrete modeling methods (2008, methodology): “In the first type [21, 24, 28, 30] (called lattice beam model), the material is discretized as a network of classical two–noded Bernoulli beams transferring normal forces, shear forces and bending moments which are calculated using a conventional simple beam theory.”
Experimental Investigations of Fracture Process in Concrete by Means of X‐ray Micro‐computed Tomography (2016, background): “In particular, the presence of aggregate particles and ITZs is important since the volume fraction of aggregate can be as high as 70–75% in concrete and the ITZs with a thickness of about 50μm are always the weakest region in usual concretes (wherein cracking starts because of their higher porosity)”
