Sažetak
The rapid development of production technologies and new materials, whose material parameters cannot be determined by conventional macroscale experiments due to their geometry, size or heterogeneous microstructure, is evident in recent years. In such cases, the nanoindentation technique can be used to experimentally assess material properties such as Young's modulus and hardness. The possibility of reproducing the load vs. indentation depth curves of the performed nanoindentation tests by means of finite element (FE) models is discussed in this work. The experimental nanoindentation measurements are herein performed on wrought as well as on AISI 316L samples attained via additive manufacturing by employing a Keysight G200 nanoindenter with a standard Berkovich tip, while applying the standard depth-controlled loading - unloading method. Since, however, the numerical simulations of nanoindentation entails a nonlinear elasto-plastic contact problem, the Young's modulus and the hardness are not sufficient to properly and completely characterize the material behaviour observed in the experimental tests. Simulations are thus performed by adopting a numerical model optimized in terms of its dimensions (i.e., the radius and the height of the model with respect to the nanoindentation depth) and employing an elasto- plastic material model. The influence of the geometrical and elasto-plastic material parameters on the quality of the simulated results is therefore systematically investigated, allowing correlations of FE and experimental data to be established.
