Abstract: Single-particle crushing tests have been carried out on the component minerals of a sand and the results have been compared statistically with those obtained for individually marked particles placed in triaxial samples and then subjected to isotropic consolidation and shear tests. The single-particle crushing strength was defined for breakage of asperities and for whole-particle fracture. The results were analysed and compared using particle survival probability curves. Maximum characteristic stresses were est… Show more

“…4. (Nakata et al, 1999) For the stresses reached in the simulations, simulation I (size effect estimated from the Weibull moduli) displays a closer match to the experimental results. Simulation II, using the 'best-fit' b-values demonstrates substantial crushing upon yield, and a rapid reduction in volume and a large gradient (.…”

“…Most of these works have examined the strength of sand particles (e.g. Nakata et al, 1999), while others have investigated the contact behaviour (Horn & Deere, 1962;Skinner, 1969;Cavarretta et al, 2010;Senetakis et al, 2013). However, it should be emphasised that while this work on sands has tested individual particles, the current work is 'micro' only in the sense that small structural elements of natural clays have been tested, not single particles.…”

“…Here the nature of a soil particle is defined as the combination of its geometry (roughness and shape) and its mechanical response (strength and stiffness). Over the past decade significant progress has been made; for example the relationship between particle strength and compression behaviour has been investigated in detail by McDowell & Bolton (1998) and Nakata et al (1999), while the discrete element method (DEM) analyses of Thornton (2000) and others have indicated a stronger correlation between the macro-scale angle of shearing resistance and inter-particle friction than the experimental work of Skinner (1969). In the small strain region, Clayton & Heymann (2001) demonstrated that particle shape can have a significant impact on stiffness.…”
