Influencing the Indentation Curves by the Tilt of the Berkovich Indenter at FEM Modelling of the Steel Nanoindentation
Original language description
The influence of the Berkovich indenter tilt on the results of the FEM modelling of steel nanoindentation is evaluated in this paper. The shape deviations of the indenter have a great impact on the results of the nanoindentation. The main deviations are the indenter bluntness and indenter tilt. The indenter tilt has an impact on the shape of the contact area and the shape of indentation curves. The X5CrNiCuNb 16-4 steel nanoindentation with Berkovich indenter was modelled and the indentation curves were obtained. The Berkovich indenter was blunted and the tilt of the indenter was changed to determine the influence of the indentation curves by the indenter tilt. The plasticity of the steel was modelled with the multilinear model of material, which was fitted to the data from tensile test. The results showed that growing tilt shifts the indentation curves to higher values of indentation forces and makes unloading curves slightly steeper which is in the agreement with larger contact area. The calculated indentation curves were compared with the indentation curves obtained by experiment and the impact of the indenter tilt to the indentation curves was determined by the comparing of the maximal forces and the shapes of the indentation curves.
