On the packing and crushing of granular materials

The importance of crushing in sands for example has long been acknowledged; when a sand is subjected to monotonic increasing stress (normal compression), it is well known that after a high enough stress is reached, particle crushing begins and causes a permanent decrease in volume (e.g. Nakata et al., 2001). Particle …

Acoustic Emission and Force Drop in Grain Crushing of …

To study the acoustic and mechanical characteristics of carbonate sand crushing, both force and acoustic emission (AE) signals were measured as a function of run time in single-particle uniaxial compression tests. Rapid large force drops corresponding to avalanches led to obvious AE signals. The AE signal analysis of carbonate sand was ...

Engineering properties of the compressibility and crushing

Carbonate sand is more susceptible to crushing, at a stress level of 1–3 MPa (Coop, 1990; Mesri and Vardhanabhuti, 2009; Yu, 2019) while silicate sand is less crushable with a high yield strength around 10–100 MPa (McDowell and Bolton, 1998; Nakata et al., 2001a; Meidani et al., 2017; Yu, 2017a, Yu, 2017b, Yu, 2017c).

Particle breakage evolution of coral sand using triaxial compression

Fig. 18 also shows the particle breakage evolution during undrained triaxial compression. The breakage rate R B decreases with the accumulated amount of Br and increases with the current effective confining pressure σ 3 ′. At the initial phase, since Br is small, the effect of σ 3 ′ on the accumulation of RB prevails.
