ABSTRACT

In this study, the statistical correlation method is utilized to describe the distribution of fractures. A two-point correlation function has been developed and applied to the fractures. This method has been implemented through three different ways, i.e., exponential method, sample method, and point-by-point method. The preliminary result shows the potential of this method to provide a

1 INTRODUCTION

Particle breakage is of great importance in determining the constitutive behavior of granular materials, especially at elevated stress level (e.g. Coop & Lee, 1993; McDowell & Bolton, 1998). Single particle crushing tests have been carried out to understand the statistical distributions of particle strength (e.g. Nakata et al., 1999), fracture pattern, morphology evolution and breakage energy dissipation (e.g., Zhao et al., 2015). These observations enlarged our understanding on particle breakage at micro-scale, which helps interpret particle breakage at macroscale and establish more realistic simulation models.
