“…It was found that the liquefaction resistance of gravelly soil increases significantly with the increasing gravel content because of the growth in number of gravel-to-gravel contact. Jiang et al [24] examined the microstructure and its evolution in granular soils subjected to cyclic loading using the DEM method. e research indicated that the evolutions of coordination number and contact fabric are highly dependent on the relative density and cyclic mode.…”

“…The behaviour during the load reversals has not been discussed in detail here, but only slight, if not negligible, changes can be observed. This is in contrast to DEM simulations, in which the anisotropy and the contact density were found to evolve more significantly [34, 35]. Obviously, the DEM still cannot capture all distinct features of the granular behaviour.…”

“…where F c is the critical-state fabric anisotropy (dependent on the Lode angle θ s of the stress tensor),˙ p q is the deviatoric part of the plastic strain rate, the loading direction n is defined as n ≡˙ Based on observations of results from DEM simulations in [40,67] and experimental studies in [86] where the Lode angle of stress is constant, it is noted that at critical state, fabric and loading direction are coaxial. In [100] the loading direction was based on the stress tensor, and it was found that the contact normal fabric tensor always tends to be coaxial with the stress tensor under cyclic loading, regardless of the specimen density and cyclic failure mode. Therefore, at the critical state the condition n F : n = 1 holds for various loading conditions.…”
