Inverse Approach of Parameter Optimization for Nonlinear Meta-Model Using Finite Element Simulation
Round 1
Reviewer 1 Report
1. The results in table 2 can be presented without the exponential form, so instead of 7.36e + 02, you can just write 736 etc. The same can be done in table 5, except for the last column.
2. In the text below table 2, the description ?? appears twice.
3. There is such a rule that the chapter of an article does not start with a drawing. The chapter should start with a text. And the drawing should be at the time it is referred to in the text. Chapters 3.1 and 3.2 start with a drawing, this shouldn't be the case.

Reviewer 2 Report
The paper approaches the subject of comparing the performances of different meta-models, using data obtained via experimental test and FE modeling for the inverse method. The study analyzes the results for the stress-strain curves obtained using meta-modeling, as well as a RMSE comparison among the meta-models.
The presented manuscript is clear, relevant for the field and well structured. The conclusions are well presented and of current use for the scientific field.
To be considered:
- Please use the paragraph spacing options presented in the guideline for authors.
- Also, the authors could insert some images regarding the testing procedure of the stainless-steel sample.
