Title
Finite-Elemente-Analyse der registrierenden Härtemessung
Abstract
The depth-sensing indentation process has been simulated using the finite element method (FEM). The quality of the finite element model was demonstrated by a comparison with analytical results. The effect of numerous parameters on the indentation curve was analysed. Especially, it was shown that the influence of the parameters of the test device and the material may be coupled. Using the finite element model some experimental results were reproduced; a very good agreement between numerical and experimental results was achieved for the investigation of a coated (TiAlN) steel specimen with elastoplastic material behaviour as well as for an uncoated steel specimen (22 NiMoCr 3 7) with viscoplastic behaviour.
