3D mesoscale finite element modelling of concrete (2017, unknown): “A typical way to work around the difficulty arising from meshing directly the highly unstructured mesoscale geometry has been to firstly perform a background meshing and then bundle groups of the meshed elements into aggregates of desired shapes [19, 30].”
Meso-scale computational modeling of the plastic-damage response of cementitious composites (2011, methodology): “However, it is found that the meso-scale concrete model using circular shape of aggregate tends to give higher strength compared to the model using irregular actual shape of aggregate [15].”
