2D numerical simulation of elasto-plastic deformation of thin hard coating systems in deep nanoindentation test with sharp indenter

In this paper hard coating systems are considered as an investigated material and their behaviour under static loading is analyzed. Experimental nanoindentation test is one of the most demanding in obtaining mechanical properties of thin films and such test is simulated using finite element method (FEM). Numerical simulation follows the experiment and it gives satisfying results in many technical and research areas. Distributions of computing values using FEM models for multilayer systems are presented in the paper. Capabilities and difficulties in simulation of thin hard coating systems are described, that is an important step to achieve further purpose, which is a complete and precise numerical analysis of properties of hard coating systems in deep nanoindentation test.
