Numerical Simulation of Aggregate Shapes of Three ...

A test method is adopted that involved summing the aggregate volumes to judge the intersection and overlap of aggregates. In the 3D random aggregate simulation (3D-RAS) structure, the shape, size, and spatial distribution of the aggregate particles resemble real concrete in the statistical sense, and fundamental aggregate diameters within the same gradation are assumed to follow random Gaussian distributions.

Three-Dimensional Simulation of Aggregate and …

A numerical technique of aggregate models was implemented with probabilistic parameters depending on statistical results of PGFs and SARs. The 3D numerical model of asphalt mixtures was assembled with three different components, and was validated by uniaxial compression tests via comparison with the laboratory result.

Detachment of coarse composite sphalerite particles …

2015-2-1 · The distributions were fitted by Gaussian function (Eq. ), where x c is the mean, b is the standard deviation and ''A'' is the height of the peak. The distribution of the particle detachment force for 300–600 μm particles conditioned with SIPX and PAX is illustrated in Fig. 12. A broad distribution of detachment force was observed for the different reagent conditions.
