Effects of the Shape and Size of Irregular Particles on ...
Although studies on the effect of shape on breakage energy are scarce, this assumption was demonstrated by Unland and AlKhasawneh in their investigation of the shape effect on breakage energy and energy efficiency with singleparticle tests on limestone. They found that the specific breakage energy of cuboidal particles varies from to J/g, which is approximately times larger than .

The model cited by the discussers (Sun et al. 2015) is based on the breakage mechanics framework introduced by Einav (2007), which results in a problematic coupling between the breakage parameter B and a single stress parameter: the isotropic stress component p (the hardening function). This coupling was shown to be unable to reproduce the behavior of a crushable material along various stress paths.

1. Introduction
The 15 mm model cohesive particle with internal initial crack and microstructure is impacted at different velocities, and an image sizedetection system is used to measure the distribution of particles size after crushing. In addition, at 45 m/s, different sizes of limestone cohesive particles are modeled and the experiment is repeated.
