Round 1

Reviewer 1 Report

The authors have studied the effects of mineral grain shape on the mechanical properties of Lac du Bonnet (LDB) granite by using the CLUMP method in the particle flow code (PFC) and uniaxial compression simulation.

 

The subject is relevant to the scope of the journal and the paper is very well organized. The work is original and there is a significant amount of new work in the paper. The paper is recommended for publication after addressing the following comments.

 

-       All the papers published on the influence of mineral grain shape on rock mechanical behavior should be addressed.

-       Please mention the reference for Figure 1.

-       Add a figure showing the model including particles, dimensions and boundary conditions.

Reviewer 2 Report

The contribution and novelty of the research must state in clear way. What is the new methods and findings in the study? How you apply the results to the real samples? 

The methodology is not clear enough. Do you provide the result only based on generated models from PFC? Is there any verification?

The reference format in the text is confusing.

How you calibrate the model?
