文摘

A simple method is demonstrated to generate fractal agglomerates. The breakage of fractal agglomerates is investigated using discrete element method. Damage ratio is influenced by impact speed, surface energy, and fractal dimension. Lower fractal dimension leads to lower agglomerate strength and higher damage ratio. Previous Thornton scaling law is generalized by incorporating fractal dimension.
