Fractal and Morphological Characteristics of Single Marble Particle Crushing in Uniaxial Compression Tests [PDF]
Advances in Materials Science and Engineering, 2015 Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice. It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and ...

Influence of real particle morphology on single particle crushing behavior of rockfill based on FDEM
Journal of Rock Mechanics and Geotechnical EngineeringParticle morphology is critical in affecting the crushing behavior of rockfill materials. In contrast, most current single particle simulations lack satisfactory morphology accuracy, and the resulting crushing modes deviate from observations to some ...
