Reviewer 2 Report
The authors conducted a vibration fatigue analysis of a simply supported cracked beam subjected to a typical load. The paper is concise yet interesting. However, some improvements are required prior to publication.
- Please check the citation guidelines of MDPI. Only the surname of the authors should appear in the citation, e.g., "Dentsoras and Dimarogonas" instead of "Dentsoras A J and Dimarogonas A D". When more than 2 names coauthored the work, it should be presented as the first surname + et al.,e.g., "Jassim et al." instead of "Jassim Z A, Ali N N, Mustapha F, et al."
- Please provide updated Figures 3, 5 and 6 with improved quality. besides, Figure 4 is missing; please check the figure numbers.
- Section 4 must be restructured. This section is called "Results", but no "Discussion" follows it, and the paper jumps to the Conclusions section (#5). In addition, the last paragraph of Section 4 is "As shown in Fig. 6, the following conclusions can be drawn". This must be presented in the Conclusions section. I feel that the discussion of the results is missing; otherwise, this is a report instead of a scientific paper.
- Please correct Ref [19] in the references list: 19. Author A D N, Author D I G J, Author J P H, et al. Vibration Damping[J]. Journal of Vibration & Acoustics, 1987, 109(1):124-124.
