Frontiers Fractal Behavior of Coral Sand During Creep
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.

Quantifying the extent of crushing in granular materials: A
2007.10.1 Grain crushing is one of the micromechanisms that governs the stress–strain behaviour of a granular material, and also its permeability by altering the grain size distribution. It is therefore advantageous to be able to predict the point of onset of crushing and to quantify the subsequent evolution of crushing.
