TL;DR: In this article, a new numerical and experimental approach for determining mechanical properties of steels is presented, based on the minimisation of error between the experimental curve (applied load-indenter displacement curve) and the theoretical curve which is a function of the studied materials.

TL;DR: In this article, the authors proposed a power-law-based penetration depth-contact radius relationship valid for most metals which are deformed plastically by parabolic and spherical indenters.

TL;DR: In this article, the authors compared the analytical models for the determination of the contact radius between a spherical indenter and an elastic-plastic material with the experimental results obtained for different spheroidized steels and those obtained numerically and with various analytical models.

TL;DR: In this article, a new method for the determination of the hardening law using the load displacement curve, F-h, of a spherical indentation test is developed. But the method is based on the study of the error between an experimental indentation curve and a number of finite elements simulation curves.

TL;DR: In this paper, two different approaches for interpretation of instrumented indentation experiments are proposed: the first approach is the application of methodology developed for spherical indentation based on models and the second approach is based on the minimization between experiments and simulated data.
