The macro-mechanical behavior of crystalline rocks including strength, deformability and
failure pattern are dominantly influenced by their grain-scale structures. Numerical …

Highlights Published literature on grain kernel damage during handling is reviewed. Types
and sources of grain kernel damage are discussed. Factors affecting the level of grain kernel …

Ballast materials forming part of railway structures are subjected to cyclic loads. As a result
of these loads, ballast densification, aggregate degradation, and lateral spread of the ballast …

The discrete element method (DEM) is developed in this study as a general and robust
technique for unified two-dimensional modelling of the mechanical behaviour of solid and …

Ring shear tests were performed in this work to investigate the characteristics of shear band
formation and particle breakage for calcareous sands sampled from the South China Sea …

A flexible pavement structure consists of mainly bonded or unbonded granular materials. In
the simulation of the behavior of these pavement materials, Discrete Element Method (DEM) …

During confined comminution of granular materials a power-law grain size distribution (gsd)
frequently evolves. We consider this power law as a hint for fractal topology if self-similar …

Although particle corner breakage has been proved to be the primary mode of particle
breakage for coral sand, current studies of pile penetration have continued to present the …

Particle breakage modifies a rockfill structure, influencing its dilatancy, friction angle,
strength, and permeability, as well as generating creep deformation, wetting deformation …
