The terms "yielding" and "plastic hardening" are used in the discipline of soil mechanics to describe the post-elastic behaviour of granular media. These "plastic" phenomena are here related to the successive splitting of grains. Grains are taken to split probabilistically; the likelihood increasing with applied (macroscopic) stress ...

 · Granular materials undergo particle crushing under the long-term load, which changes the particle size distribution (PSD) of the material, and then affects its mechanical properties, so the problem of its long-term stability issues is outstanding. Previous research indicated that the crushing characteristics of coral sand particles have an effect on the creep under constant load. In order to ...

Crushing Of Granular Materials The Consequence of Particle Crushing in Engineering Properties of Granular Materials written by Omar H. Al Hattamleh Hussien H. Al-Deeky Mohammad N. Akhtar published by International Journal of Geosciences Vol.4 No.

This chapter presents recent developments made by the author in providing an understanding of micromechanics of yielding and plastic hardening of granular materials and the role of particle crushing in determining the constitutive behaviour. It will be shown that there is nothing "special" about soil; breakfast cereals and pasta have normal compressionlines similar to soil. […]

The fractal crushing of granular materials ScienceDirect Crushing of granular materials 2095 suggests that if each of the particles is now to have the same probability of splitting, then (dV(uja,r d^ (42) (dl22 Or/ao)" ^oJ (32) (49) ie a = 1 If a 2, then clearly the larger particles have a greater probability of splitting, and this will tend to scavenge the larger particles out of the aggregate

Abstract A study has been made of the micro mechanical origins of the irrecoverable compression of aggregates which comprise brittle grains. The terms "yielding" and "plastic hardening" are used in the discipline of soil mechanics to describe the post-elastic behaviour of granular media. These "plastic" phenomena are here related to the successive splitting of grains. Grains are ...

 · This paper presents a micro and macromechanical model to estimate the grading evolution and plastic strain caused by particle crushing in the isotropic compression of granular materials. A joint‐probability particle crushing criterion of the maximum contact force and the particle strength is proposed to calculate the incremental particle crushing probability.

 · 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 ...

 · Fractal theory, which employs statistical concepts in order to explain particle crushing, may provide a solution to this problem. The particle size distributions are introduced to determine the fractal dimension. The relationship among the particle size, the crushing strength, crushing energy and the probability of survival of the particles are ...
