Fractal Behavior of Coral Sand During Creep

open access: yesFrontiers in Earth Science, 2020
Granular materials undergo particle crushing under the long-term load, which changes the particle size distribution (PSD) of the material, and then affects its mechanical properties, so the problem of its long-term stability issues is outstanding ...

Experimental investigation on mean crushing stress characterization of carbon–epoxy plies under compressive crushing mode [PDF]

open access: yes, 2013
A challenge in numerical simulation of crashworthiness study is to be able to predict the crush damage modes, their evolution during crushing and the energy absorption in any composite structure from elementary material characterisation data.

Effects of controllable shock wave on particle size characteristics of tin polymetallic ore crushing products

open access: yesJournal of Materials Research and Technology, 2023
Different minerals in tin polymetallic ores have varying degrees of grindability. When the particle size distribution of the crushed ore is unreasonable, sufficient liberation of useful minerals necessitates an increase in the grinding time, resulting in

Crushing Mechanism for Soil Particles

open access: yesWorld 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 ...

Breakage Functions of Particles of Four Different Materials Subjected to Uniaxial Compression [PDF]

open access: yes, 2015
Particle breakage is a common problem in the conveying and handling of particulate solids. The phenomenon of particle breakage has been studied by experiments by a number of researchers in order to describe the process of breakage by mathematical ...

Evolution of particle crushing of carbonate sands under cyclic triaxial stress path

open access: yesYantu 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

open access: yesYantu 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

open access: yesKSCE 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.
