On the packing and crushing of granular materials

Mar 15 2020 0183 32 1 Introduction The packing characteristics of granular materials have been studied for over a century It is generally accepted that the comparative density of any granular material is a function of particle shape size range and size distribution Burmister 1938 however predictions for the density or porosity for a granular assembly are usually empirical and are only semi-analytical at...

Statistical study of the crushing of limestone grains

The behavior of granular materials subjected to shear loading is often very complex to be correctly characterized Loads on a discrete medium composed by several grains lead to a diffusion of stresses in the medium by contact and frictions between individual grains This stress diffusion combined to inter-granular relative movements induces some cracking in the contact zones and even some...
