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.

Influence of particle breakage on scale effect of filling characteristics of rockfill material

open access: yesYantu gongcheng xuebao, 2020
The filling characteristics of rockfill materials are closely related to their mechanical properties. They can be changed by particle breakage, which is one of the main factors of the scale effect of rockfill materials.
