By means of two dimensional contact dynamics simulations, we analyzed the effect of the particle size distribution (PSD) on the shear strength of granular materials composed of un-breakable discs. We modelled PSDs with a normalized beta function, which allows for building S-shaped gradation Read more... about Does modifying the particle size distribution of a granular material alter its shear strength?

Significant developments in numerical modelling have been achieved during the last decade, but validation of these techniques is required to build up confidence. As these developments represent a significative advance for mining geomechanics, this paper focuses on the application of the Read more... about Estimation of Rock Mass Strength Using the Synthetic Rock Mass (SRM) Approach and Particle Flow Modelling
