The Breakage of Shape-Anisotropic Particles under Normal Contact with Different Particle Shape Parameters

open access: yesApplied Sciences, 2021
This paper elaborates the cone–hemispherical gypsum particle breakages under normal contact with different particle shape parameters (contact diameter d, cone angle θ and sphere diameter D) and proposes a simple quantitative approach to discriminate ...

Breakage of flawed particles by peridynamic simulations [PDF]

open access: yesComputational Particle Mechanics, 2021
In this paper, we use a 2D bond-based peridynamic model to investigate the strength of disk-shaped particles including pre-cracks. We use a diametral (or Brazilian) test to break the particles. For the flawless particles, we find that the stress distribution compares well with an analytical model accounting for the size of the contact zone, and the ...

Particle breakage and shape evolution of calcareous and quartz sands under compression

open access: yesYantu gongcheng xuebao, 2022
The influences of particle breakage on the mechanical properties of soil are significant. The previous studies mainly focus on the variation of particle size during particle breakage but neglect the change of particle shape.

Particle breakage and morphology changes of calcareous sands under one-dimensional compression loading

open access: yesMarine Geophysical Research, 2022
Particle breakage and the corresponding change of morphology are two key factors governing the mechanical behavior of calcareous sands in offshore geotechnical engineering constructions. To reveal the characteristics of these two factors, oedometer tests

Effects of the Shape and Size of Irregular Particles on Specific Breakage Energy under Drop Weight Impact

open access: yesShock and Vibration, 2019
Particle shape and size are main factors influencing particle breakage. Single-particle breakage tests were conducted on irregular magnetite ore using modified drop weight impact equipment to analyze the effect of shape and size on specific breakage ...

Experimental Investigation on Particle Breakage Behavior of Marine Silica Sand under High-Stress Triaxial Shear

open access: yesJournal of Marine Science and Engineering, 2023
There is often obvious particle breakage for silica sand under high-stress, which will lead to the bearing capacity reduction and excessive settlement of the foundation.
