Meso-Simulation and Experimental Research on the Mechanical Behavior of an Energetic Explosive

Round 1

Reviewer 1 Report

The article titled "Meso-Simulation and Experimental Research on the Mechanical Behavior of an Energetic Explosive" is interesting from a scientific point of view, bit it does not go with into the line of the journal where it was submitted for publication. A change of the magazine may be considered, because may cause problems with finding this article by people interested in this topic.

Detail remarks:

In Figures 10 and 11 there should be a scale in range of dimensions and stress.

Figure 14 should presented the object from a perspective from which the position and angles of sensors placement are visible.

Figure 16 in its current form does not bring any relevant information. It may be considered, to be replaced by two photographs that show the measurement method and results visible on the screen on a larger scale.

In Figure 19 the 1/3 part of the picture shows a frame that does not bring any new information. This photograph should be taken from a perspective from which the ways of causing stress are clearly presented.

In Figures 17 and 20 the measurement points of the should have the measurement uncertainty range marked.

The process of preparation of the samples presented in Figure 18 should be more precisly described together with their dimensions.

The approximating functions presented in the Figures 6, 10, 17, 20 should be characterized additionally with the correlation coefficient.

In the conclusions should not be presented a description of the problem, but it should be focused on the achievements and results obtained through the research.

Reviewer 2 Report

The paper “Meso-Simulation and Experimental Research on the Mechanical Behavior of an Energetic Explosive”, by Qinxue Pan, Shuangyang Li, Yang Liu, Xiaoyu Xu, Meile Chang and Yunmiao Zhang, presents an interesting study in order to propose a model related to polymer bonded explosives (PBX) material properties. Generally, the paper is well written, and the information is clearly presented.

The paper is recommended for publication with minor revisions:

1. In Figure 1 authors are asked to insert a reference, if the draw is not original.
2. In Figure 3 authors are asked to re-design the image by inserting some explanations in the image. There are some dash lines, blue/red particles, etc. what should represent in accordance with the inserted process description?
3. In Figure 5 c) are really oval particles or is related with the view angle? What is the purpose of using oval particles, and not cauliflower shape, or something else?
4. In Figure 7 what is the difference between blue and red particles? Only the size?
5. In section 4.1 the authors discussed a theoretical model by using a 20-26 µm grid. What is the size of the particles for this grid dimension?
6. In Figure 8 the authors are asked to insert more explanation in the image. The reader will see only 2 triangles, 1 square and some arrows. What represent them in the image?
7. In section 4.2 the authors have chosen the Hanning window function. What is the advantage, because there are many window functions, e.g. Hamming, Blackman-Harris, Rosenfeld, etc..?
8. In Figure 12 please insert the complete graph. Is not visible the last frequency value related to the last point (according to the text it should be 8MHz).
9. In Figure 17, the same, please insert the complete graph. Is not visible the last frequency value related to the last point (according to the text it should be 10MHz).

Round 2

Reviewer 1 Report

Figures 9 and 11 have been supplemented with a scale, but its resolution is too small, which makes it unreadable. Moreover, the yellow background color in these figures has appeared which it reduces their legibility and should be removed.

The standard deviation in Figures 17 and 20 is specified with an accuracy of 5 decimal places. This value is supposed to determine the accuracy of the position of the measuring point and one would have to consider whether such accuracy is needed.
