Dec 01, 1997 ELSEVIER Engineering Geology 48 ( 1997) 1855 198 Fractal models for the fragmentation of rocks and soils: a review E. Perfect Department of Agronomy, University of Kentucky, Lexington, KY 40546-0091, US,4 Abstract Fragmentation, the process of breaking apart into fragments, is caused by the propagation of multiple fractures at different length scales, Such fractures can be

Fractal models for the fragmentation of rocks and soils: a

Soil fragmentation is the result of tillage and planting operations. Fractal theory, which deals with the scaling of hierarchical and irregur systems, offers new opportunities for modeling the fragmentation process. This paper reviews the literature on fractal models for the fragmentation of heterogeneous brittle earth materials.

Fragmentation Fractal Analysis on Particle-size

Apr 01, 2003 Particle-size distribution in soils is one of the most fundamental physical properties of soils. One of the latest developments in the study of particle-size distributions has focused on the use of fractal theories. In this study, the fragmentation fractals were used for determining the characteristics of the particle-size distribution curve.

EVOLUTION OF FRACTAL DIMENSION OF PARTICLE BREAKAGE

The quasi fractal dimension increases with the increases in the failure stress and breakage energy, and trends to a constant value 2.60 or so. This limit value of the fractal dimension is called as the intrinsic fractal dimension. Relation of the quasi fractal dimension to the failure stress and breakage energy is proposed based on the Weibull

Aug 29, 2018 The relationship between fracture aperture (maximum opening; d max) and fracture width (w) has been the subject of debate over the past several decades.An empirical power law has been commonly applied to relate these two parameters. Its exponent (n) is generally determined by fitting the power-law function to experimental observations measured at various scales.

A fragmentation-spreading model for long-runout rock

Dec 01, 1999 Rock fragmentation produces high-velocity fragments moving in all directions, resulting in an isotropic dispersive stress within the translating rock mass. A longitudinal dispersive force consequently acts in the direction of reducing mass depth and tends to cause the rear part of the avalanche to decelerate and halt and the front part to
