AE Signature Interpretation of Single Particle Crushing under Uniaxial Compression [PDF]
E3S Web of Conferences, 2019 Granular soils exhibit particle crushing under certain loading circumstances, and it significantly affects their mechanical behaviour. However, the estimation of the particle crushing is extremely challenging.

Calculating the state parameter in crushable sands [PDF]
, 2019 The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

Crushing Mechanism for Soil Particles
World Journal of Mechanics, 2020 Typically, soil samples must be crushed into particles for laboratory research. Thus, an efficient mechanism to ensure a uniform particle size is essential. We previously developed a rod mill device that performs well, but video analysis indicated that the shear forces applied by the rod were more effective than the compressive forces applied by the ...

Implicit DEM analyses of size and shape effects on crushing strength of rockfill particles
Yantu gongcheng xuebao, 2023 An implicit version of discrete element method (DEM) called non-smooth contact dynamics (NSCD) is used to simulate the crushing process of single rockfill particle under one-dimensional (1D) compression.
