A statistical investigation of particle crushing in sand

2011-8-2 · The significance of particle crushing in the stress-strain behaviour of sands has long been recognised. McDowell & Bolton (1998) have related success-fully the normal compression line of sand to fractal crushing of particles, while Cheng et al (2004) have identified the yield surface of a sand as a contour of crushing.
