Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates

Particle breakage in soils is a well-recognised behaviour. Conventional methods for quantifying the process rely on calculating area between particle size distribution (PSD) curves produced before and after crushing. A key aspect of understanding across different size/sieve fractions. Grading entropy coordinates allow representation any PSD to be shown as single point Cartesian plane are able track grading evolution with relative ease. In this study, compared three commonly used indices (Br, Br* IG). It that advantageous over traditional subtle changes directly provide further insight regards individual fraction sizes. also discussed conventional measures dependent assumptions an initial and/or final PSD. contrast, depend only characteristics (current) curve. was observed captured by determine rate at which differently sized particles break take stress. Moreover, it suggested may stress path dependency, feature not present indices.
