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 ...
