Reviewer 2 Report
The authors used finite element analysis was used to verify if the MFL signal exists at the large lift-off. They combined magnetic sensing and coupling and weak analog signal processing method. My constructive criticisms of the article are itemized below:
- How did the authors obtain the material parameters used in the FEM analysis?
- Superficial comments about the computational model. It is not clear to me how the authors apply this method.
- Regarding the FEM model, the paper does not report any aspect associated with the convergence of the FE model. The convergence is a critical issue, both in terms of the quality of the solution and its ability to go beyond global displacements and quantify internal stress resultants and the corresponding stresses, and in terms of the computational load associated with the analysis.
- The experimental setup must be better explained. How many structures are analyzed for each condition? Also, how the authors treat the aliasing and leakage phenomena?
- In figures 27, 28, 30, 32 and 34, the authors nee to increase the size of the axes.
- The limitations must be discussed by the authors and to the related need of further work.
