Much research has focused on the micro-mechanics of sand particles. The single particle uniaxial compression test is a common way to study breakage behaviour. However, there is still little agreement on particle breakage criteria and the mechanisms of breakage remain uncertain, partly because of the often rapid brittle failure of sand particles. In this study, a …

Therefore, wash sand included a more broad distribution of grain sizes, which correlated with a greater resistance to compression. The surface strength of wash sand (15.4±6.2 kPa, N=5) was more than three times that of dune sand (4.7±2.1 kPa, N=5), which was a highly significant difference (unpaired t-test, P<0.001).
