Reviewer 1 Report

Dear Authors,

thank you for the interesting work. There are only some small parts that need revision. First, the symbols in the text are not perfectly matching the formulas and figures. Please check for form and subscript, etc. Further, there is only one table, but in the text 2 tables are mentioned. There seems to be something missing. Same thing for Fig. 4, where in the text it is said µf and Sf from eq. (30) could be found in there, but they are not. In the experimental results you investigate both healthy and cracked condition. Can you please give some information on how the crack was realised in the experiments? This is of great importance for anyone who would like to reproduce your results.

Best regards
