Study of Dynamic Failure Behavior of a Type of PC/ABS Composite

Round 1

Reviewer 1 Report

I find that the paper entitled: "Study of Dynamic Failure Behavior of TC-45M Composites" is an interesting.

In this paper was presented the research of properties of the TC-45M Composites. TC-45M composites were subjected to uniaxial tensile tests at different speeds and temperatures. A high-speed video camera filmed the samples' deformation process while they were at room temperature. The results show that such composites have more obvious temperature effect and strain rate effect, the yield stress decreases with the increase of temperature and increases with the increase of strain rate. The yield stress is linearly dependent on temperature and the logarithm of the strain rate. The parameters of the J-C constitutive model determined by the inversion method are the constructed parameters of the constitutive model can be well applied to describe the high strain rate tensile test. The J-C constitutive model determined by the inversion method and the analysis results obtained by the DIC served as the basis for this simulation. The uniaxial tensile tests at room temperature and various strain rates were numerically simulated and compared with the test results, which were able to reproduce the test process, proving that this parameter can be applied to TC-45M composites.

However, all the information listed in the paper is of a technical nature, without innovation and detailed analysis of the possibility of overcoming deformation and breakages. I believe that the authors should seriously improve the work from the aspect of innovative approach in overcoming all the mentioned deformations.

Accordingly, I recommend the Accept after minor revision (corrections to minor methodological errors and text editing).

Reviewer 2 Report

The present paper studies the dynamic failure behavior in TC-45M composites. The response considered is uniaxial tensile at different temperatures and strain rates. The study indicates that as the temperature increases, the elastic limit decreases and the deformation increases To verify this, an experiment was designed on the intrusion of TC-45M compounds into the plate.

It is an interesting work, very specific, on a poorly defined material. TC-45M features not shown. It is something that must be made clear before starting rehearsals. The layout of the work is followed well and presented strikingly.

It must be corrected: In the title replace TC-45M with its corresponding name.

Indicate in the text the characteristics of the mentioned material.

Lines 177, 260: the equations must be outlined in the text

Reviewer 3 Report

The manuscript deals with an interesting topic, having an exceptional technical background but poorly structural presentation, as well as argumentation imperfections that could be first addressed, prior it to be accepted for publication at the Materials journal as is.

1. The following 5 subsections: 2.1, 2.2, 2.3, 3.1, 3.2, are deprived from citations, thus, authors are recommended to better verify and to validate their test, results and findings by adding selected citations that are referring to the relevant narrative flow.

2. Similarly to the above, authors could check all Figures and Tables’ data and to add in their captions the relevant citations from which they have been recalled-adapted from.

3. In super-Figures containing 2 or more subgraphs it is not clear what is the conceptual logic of hidden information from one to the other. For this, authors are recommended to devote a more systematic and descriptive analysis per each one, disclosing such hidden information that is difficult to be perceived from the readers themselves.

4. The technological background of the study is fully conveyed and satisfactorily developed but it is not straightforward if the examined “Dynamic Failure Behavior” study could be also useful and applicable to other than that of the TC-45M composites?, or it is necessary all analysis and testing to be taken from the beginning in any separate type of such a composite? For this, a succinct explanation of 3-4 sentences can be given.

5. The concluding remarks cannot contain numerical parts of the findings, but only generalized conclusions, testing constraints, technological challenges, derived from the analysis but be also applicable to similar research topics, accordingly. The numerical part can be transferred to the preceding sections, accordingly.
