Modelling the mechanical strength of fractal aggregates

摘要: Abstract Variations in the mechanical strength of aggregates with aggregate cross-sectional area have been modelled this work. The fractal structures were considered conjunction fundamental mechanisms formation and rupture during modelling. A quantitative expression porosity characteristic length terms dimensions was derived from dimensional analysis. Predictions Rumpf's equation demonstrated that tensile strengths decreased increasing area. An experimentally determined function introduced into model to account for effect on strengths, enabling one predict compression aggregates. predictions agree well experimental data measured latex when compressed between two parallel plates.
