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 ...

Evolution of particle crushing of carbonate sands under cyclic triaxial stress path
Yantu gongcheng xuebao, 2019 The carbonate sand is widely distributed in the South China Sea and used as the fill materials for land reclamation. Carbonate sand particles are fragile and can be easily crushed, making the carbonate sand exhibit distinctive mechanical behaviors ...

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.

Fractal crushing of solid particles
KSCE Journal of Civil Engineering, 2017 It does not have widely accepted theory to study particle crushing up to now because of the complex and irregular physical structure of the particles. Fractal theory, which employs statistical concepts in order to explain particle crushing, may provide a solution to this problem.
