Breakage of flawed particles by peridynamic simulations [PDF]
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
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.
