N2 - This paper aims to provide a comprehensive guide to the application of the inverse technique to the miniaturized tests, on material parameter identification, without investigating the aspects related to the correct choice of a specific material model. Firstly, a brief introduction to the fundamental principles and procedures associated with the inverse method is given. In general, the strategy described relies on the coupling of the finite element (FE) modelling with an optimization scheme. The FE method allows for the evaluation of the response of the material under various types of tests, test conditions, and complex constitutive equations, and avoids the use of approximation techniques for the interpretation of the experimental results. Then, on this based, an example of FE-based inverse processes using small punch creep tests is given to illustrate the process and capability of identifying the creep damage properties. Finally, several sensitive issues, related to the application of the inverse approach, are addressed.
