On the role of particle breakage in the shear failure behavior of granular soils by DEM (2013, background): “[29] is followed to achieve an initial uniform void ratio of 0.”
DEM analysis of bonded granular geomaterials (2008, unknown): “This is an effective technique of sample generation since it allows the generation of a homogeneous network of contact forces and particle distribution within the created samples; it is computationally efficient and avoids the onset of high lock-in contact forces, the equivalent of self-stresses in ”
A virtual experiment technique on the elementary behaviour of granular materials with discrete element method (2013, methodology): “It could be done using various methods [29] and lead to different initial internal structures.”
Effect of sample size on the response of DEM samples with a realistic grading (2014, methodology): “The calculated unbiased sample variances of void ratio have been used to quantify the degree of homogeneity by Jiang, Konrad, and Leroueil (2003) and are also adopted here.”
