Validation of the log e–log σ normal compression law using particle strength data

Abstract

This note is a study of experimental data on particle strength and normal compression, to establish whether the normal compression law proposed by McDowell and de Bono in 2013 is supported and confirmed. A number of different sands are examined and found to support the hypothesis. In addition, some new simulations on sand mixtures are used to explain experimental results for quartz–feldspar mixtures. It would appear that the proposed compression law is also supported by the data for the sand mixtures.
